The Art of Impossible Wonders in the Palm of Your Hand
JBSteeven Teams is a collective of close-up magic designers, storytellers and 3D engineers — crafting moments of genuine astonishment, one gimmick at a time.
From elegant sleights to impossible transpositions — our card work is rooted in classical technique elevated by modern design thinking.
Sleight · Gimmick · VisualCustom PLA-printed mechanisms engineered for reliability, natural handling, and effects previously thought impossible in close-up conditions.

Mental · Prediction · ForceThe Pharmakon Series
An entire performance act built around a medicine box, a printed receipt, and a bus ticket — three objects your spectator carries every single day. Nothing is switched. Everything is examined. The impossibility lives in plain sight.
Every effect we design comes with a narrative architecture — a story that transforms a clever trick into a moment people describe to strangers for years.
Script · Frame · ArcPeek inside our development pipeline — from concept sketch to final PLA prototype, with full documentation of every iteration and failure along the way.
CAD · Print · Test · ReleaseA creative studio where magic design meets engineering precision — and where every effect begins with the question: "What would make someone truly believe?"
Our Three Pillars
Every gimmick begins on a CAD workstation. We iterate through multiple PLA prints before a mechanism earns its place in performance. Tolerances measured in tenths of a millimeter.
A trick without a story is a puzzle. We script the emotional arc of each effect — the setup, the tension, the impossibility, and the aftermath that lingers for days.
The mind is the greatest gimmick of all. Our mentalism work layers psychological technique with physical method — each reinforcing the other invisibly.
Development Process
Every project begins with the desired spectator experience written in plain language. What should they feel? What impossible thing must they witness? Only then do we work backwards to method.
CAD modeling followed by iterative FDM printing in PLA. Each print is tested for action smoothness, angle-proofness, and ability to withstand handling stress over hundreds of repetitions.
The script is written and refined. Psychological subtleties are layered in. Misdirection is choreographed with the movement of the effect itself — nothing is accidental.
Real spectators. Real reactions. We record and analyse every test performance, refining timing, angles, and scripting until the effect fails to register as method at every angle.
Full PDF teaching notes, video tutorials, and gimmick files are produced. We release nothing we wouldn't perform ourselves at the closest possible distance.
Card Magic
Sleight of hand, gimmicked decks, and impossible transpositions — all designed for the close-up environment.
Our Philosophy on Cards
A playing card is the most scrutinised object in magic. Your spectator knows what it looks like, how it feels, how heavy it is. Designing effects with cards means designing against the most educated observer imaginable. We love that constraint.
Signature Effects
A selected card is pushed face-down into the middle of the deck. Moments later, its image bleeds through the back of the top card — visible, tangible, photographic. A custom PLA-printed insert makes this angle-proof from 360°.
Two cards in two different spectators' hands simultaneously swap positions with a word. No sleight of hand — the mechanism is entirely contained within a gimmicked card printed in PLA with embedded micro-hinges and tension springs.
Before the performance begins, a card is written on and sealed inside a small medicine box. The spectator names any card. The box is opened. Impossibly, the written card matches — the performer never touched the box.
An entire shuffled deck reverses itself face to back while resting in the spectator's own hands. The performer's hands are in full view throughout. The solution required six prototype iterations of a PLA deck-cradle mechanism.
Core Handling Principles
Every gimmick we create must sit in the hand without tension. If a performer's hand looks natural, the spectator has no reason to look. We test every hold against high-resolution photography of genuine card handling.
Close-up audiences sit, stand, and wander. We design for 180° minimum — and target 360° whenever mechanically possible. Our PLA gimmicks include angle-stop features machined directly into the geometry.
A close-up performer may work twenty tables in an evening. Any effect that takes longer than 30 seconds to reset is a liability. Reset time is a first-class design requirement, not an afterthought.
Where possible, everything should be examinable after the effect. The spectator who picks up the card and finds nothing wrong will talk about that moment for years.
3D Printed Gimmicks
PLA-engineered mechanisms that push the boundaries of what close-up magic can achieve at one foot.
Why PLA?
PLA (Polylactic Acid) offers the ideal combination of properties for magic gimmicks: lightweight, printable with tolerances under 0.2mm, takes paint and varnish cleanly, and is skin-safe. Unlike metal mechanisms, it produces no sound signature when activated — critical in close-up silence.

Design Specifications
Layer heights of 0.1–0.15mm for gimmick surfaces. Structural components printed at 0.2mm with 40% infill for strength-to-weight ratio.
All visible surfaces receive primer, sanding, and acrylic finishing. Card-facing surfaces use micro-texture to match real deck stock.
Critical for card gimmicks — PLA shells are weighted with calibrated steel inserts to match the exact gram-weight of standard Bicycle or USPCC stock.
All moving parts use felt or silicone damping layers. Zero mechanical noise under performance conditions. Tested in rooms below 30dB ambient.
Every mechanism is stress-tested to 2,000 activations minimum before production release. Field performers report 10,000+ cycles without failure.
Bespoke gimmick design available. Bring us your impossible idea and we'll spend the engineering hours to make it real. Minimum 4-week development timeline.
Everyday Object Magic
When the most ordinary things become impossible — a medicine box, a crumpled receipt, a bus ticket.
Objects We Work With
Prediction sealed inside. Spectator's thought materialises.
Torn and restored. A number on the receipt predicted.
Serial number force. Ticket becomes the prediction object.
Spectator's own screen displays the chosen card number.
Borrowed coin vanishes from sealed medicine box interior.
Bends under no touch. Returns straight — examined freely.
Thought written by spectator matches sealed prediction text.
Thought-of word appears written on a page no one touched.
The Medicine Box — Deep Dive
Our most developed everyday-object effect system.
A genuine over-the-counter medicine box is modified with a hidden PLA-printed liner. The liner contains a prediction window and a one-way mirror panel invisible from outside the box.
A psychological force is used — no mechanical switch required. The spectator freely names a card, guided by a specific patter structure developed over 140 test performances.
The spectator opens the box themselves. Inside, sealed in a folded piece of paper tucked under the blister pack, is the prediction. It matches exactly. The box can be examined and kept.
The spectator keeps the box. The PLA liner is undetectable in casual examination. Six months later, they find it again — and still can't explain it.

Mentalism
Psychology, prediction, and the slow unravelling of the spectator's certainty about their own thoughts.
The Mentalism Difference
Close-up mentalism operates in a different register to stage mind-reading. At two feet, every micro-expression is visible, every breath audible. This is not a limitation — it is a superpower. Intimate mentalism is devastating in a way nothing on stage can achieve.
Guiding a spectator to a predetermined choice through conversational structure, timing, and cognitive bias exploitation. Our scripts have been tested across 300+ performances with a 94% force rate.
Sealed, witnessed, timestamped. Our prediction systems use everyday objects — envelopes, medicine boxes, locked phone screens — to establish impossibility before the performance even begins.
Observation-based character profiling integrated naturally into performance patter. We teach the performer to read the spectator in the first 30 seconds and adapt the act accordingly.
Birthday mathematics, PIN prediction, lottery-style effects — all using genuine seeming-random numbers generated by the spectator with zero apparent control from the performer.
Signature Mentalism Effects
Spectator thinks of a deceased relative — name, face, one word they associate with them. The performer writes three things on a card and places it face down. The spectator speaks the word aloud for the first time. The card is turned over. All three are correct.
A spectator hands over their most recent shop receipt. The performer predicts the transaction ID number — a 12-digit code — written on a piece of paper sealed in a medicine box presented at the start of the session.
The performer holds a transit ticket — the spectator's own — and describes the journey taken: not just origin and destination, but the seat, the weather outside the window, and one person who sat nearby.
Storytelling
A magic effect without narrative is a demonstration. With narrative, it becomes a memory that never fades.
The Five Narrative Structures
The performer positions themselves as the inheritor of an old and nearly-lost tradition. Playing cards become "the original prediction system", the medicine box becomes "a container of sealed knowledge". This frame gives the spectator permission to believe — it situates the impossibility in a larger context of human mystery.
The effect is presented as something that happened to the performer — a strange experience, an unexplained coincidence. "I can't explain why, but every time I do this, the same thing happens." This removes the performer's agency, making the effect feel like a natural phenomenon rather than a trick.
The spectator is not the audience — they are the protagonist. "You have an unusual gift. I noticed it the moment you walked in." When the spectator believes they caused the miracle, the effect bypasses their critical faculty entirely. Resistance collapses.
Position the effect as a test, a study, an experiment. Use precise language, apparently neutral instructions, and clinical calm. When something impossible occurs within this rational frame, the contradiction is devastating — the spectator's logical mind offers no protection.
"I'll show you something I don't usually show people." Exclusivity and intimacy. The effect becomes a private gift, something the spectator was chosen to receive. They leave feeling special — and the performer leaves having given them something genuinely real.
Patter Engineering
The first 15 seconds establish everything. We write opening lines that are specific, surprising, and personal — referencing something the spectator carries to immediately create the sense that this was prepared for them specifically.
Silence is a performing tool. A three-second pause before the reveal doubles its impact. We time and notate exact pauses in our scripts — treating them with the same precision as the physical moves.
Elements introduced in the opening must return — transformed — at the climax. A word mentioned casually at the start appears on the prediction card at the end. The spectator feels the design of it. That feeling is magic.
We avoid "watch carefully" and any language that invites the spectator to look for the method. Instead: "notice", "feel", "I wonder if you'll find this as strange as I do." Language that opens, not closes.
Core Techniques
Sleights, controls, and handling principles refined for the close-up environment.
Card Controls
A one-handed cut that secretly controls a selected card to any position while appearing completely casual. Our variant includes a PLA-assisted mechanical memory aid built into the card case.
Reading the identity of a selected card during an apparently fair replacement into the deck. Uses natural light reflection and a micro-bevel printed into our custom card cases.
A riffle force that creates no visual tell and leaves the spectator with the sensation of complete free choice. Success rate 96%+ when the accompanying patter script is followed precisely.
Moving a card from palm to deck during a completely natural shuffle. Works within 12 inches — designed specifically for close-up table work where angles are uncontrolled.
Object Techniques
Reading information from inside a sealed envelope or folded paper during natural handling. No mechanical tear or window — purely physical angle work combined with deliberate grip choreography.
Exchanging the interior contents of a medicine box in a single motion during a natural handling sequence. The spectator's eyes are naturally directed away by scripted conversational cues.
Extracting written information from a folded receipt during a handling phase. The receipt is folded by the spectator themselves — our technique works with any standard fold pattern.
Forcing the reading of a specific serial number from a transit ticket using psychological pre-framing and strategic partial revelation. Creates the appearance of genuine free reading.
Recommended Study Path
Master the overhand shuffle, basic riffle force, and one-card palm. These three techniques open 70% of all card effects. Practise in front of a mirror for minimum 30 minutes daily.
Introduce medicine box handling, billet work, and the clean peek. Begin working with PLA gimmick assists to reduce technical difficulty while increasing effect cleanliness.
Write and memorise full performance scripts for three effects. Perform for real spectators minimum twice per week. Record every session and review with critical attention to timing and misdirection.
Assemble a 12-minute close-up act with clear structure, emotional arc, and 3–4 climactic effects. Begin integrating mentalism techniques. Develop a personal performing persona and voice.
