Learn the amazing closer Henry Harrius has used to end his card sets for more than 15 years.

“The Mystery Card Box” is Henry’s secret weapon for strolling or table-hopping card magic. It is the most natural and organic approach to the “Mystery Box” plot you’ll ever see. A signed card appears inside a card box in one of the fairest and most impossible ways.

Since the devious gimmick is always ready to go in your card box, you don’t have to worry about any extra pocket space or weird props. With just a deck of cards and a Sharpie in hand, you’ll be ready to blow everyone’s minds.

“The ‘Mystery Card Box’ routine is absolutely amazing. Henry got so many details in terms of movement, eye motion, misdirection…It’s one of the best things I have seen.” Simon Aronson

The cards are removed from the box, which is casually tossed to the side as you begin your favorite signed card routine (like “The Ambitious Card”.) As your routine comes to an end, you direct everyone’s attention to the card box which is still very far away from you and has not been touched since the start of the routine.

With a clearly empty hand, you pick up the box and give it a shake. Something is rattling inside. The top is opened and a folded card is shown inside. You tip it out into the participant’s hands. They unfold it themselves to discover it’s the signed card. Everyone will freak out!

Built for Workers, By a Worker

Here’s the best part. You put the deck back into the box and you’re already reset for your next group. Combine this with the fact that “Mystery Card Box” can also be performed with OR without a table, and you'll quickly realize it is a worker’s dream.

The ingenious “Mystery Card Box” gimmick is designed to fit right into your Bicycle card box. So when your card box gets worn out, all you need to do is swap the gimmick into a new one. This is a durable gimmick built to last a lifetime.

Each handmade “Mystery Card Box” gimmick comes with a complete 1 hour tutorial teaching two professional routines. This includes a remarkable Card Under Box effect that ends with the card actually landing INSIDE the box. Henry also teaches the Mercury Card Fold in exceptional detail and offers lessons learned over 15 years of performing “Mystery Card Box” to ensure that even those who are newer to card magic have everything they need to start learning this effect.

Customer reviews for Mystery Card Box



Henry Harrius' Mystery Card Box is a winner! The two routines included are both excellent. However, I've been doing card under glass/bottle for years and have also used James Brown's Card in Box as well. But using the best from each is now a miracle made in heaven! I strongly recommend Harrius' finale!!



Absolut genial und sehr durchdacht!
Bereits das Instruktionsvideo ist der Preis mehr als wert, denn es beschreibt mehrere Routinen bis ins kleinste Detail. Sehr gut gemacht.


Laura Bautista

This gimmick is perfect for performing crazy productions within the deck box. The Card-to-box routine is taken to another level with this wonderful idea. It's simple to set up and super easy to take to the stage. You only need a few minutes of the explanatory video to understand how it works and put it into practice. It's still early to be 100% sure, but it seems durable and robust.

  • Tom asks: A few questions: 1. It says it fits into your card box. Does this require any arts and crafts to your original box? 2. It says it’s a durable gimmick. What does this mean exactly? Cardboard? Plastic? 3. Is the entire routine shown in the full performance taught in full? Thanks!

    • 1. Vanishing Inc. Magic responds: It requires very little arts & crafts, will be good to go in around 2 minutes, the entire routine is taught on the tutorial, the gimmick is made from a number of different materials
  • David asks: What is the skill level of using this, can it be used by a beginner / intermediate? What slights are there to know? (guessing MCF is one of them).

    • 1. Vanishing Inc. Magic responds: This is intermediate. There is a MCF involved including any moves in the main routine but also the handling of the gimmick itself.
  • Trevor asks: Is it possible to adapt the gimmick to work with a different back design, say Tally-Ho?

    • 1. Vanishing Inc. Magic responds: If you are really skilled in card gaffing, then it’s possible but I wouldn’t recommend taking apart the gimmick to do so.
  • Justin asks: Can the card box be shown empty after the dump out and/or inspected?

    • 1. Vanishing Inc. Magic responds: It cannot be shown empty and cannot be inspected
  • Mark asks: Is it possible to use a different fold--the kind that appears in one of Eugene Burger's books (a "triple" fold, I guess we can call it)? Or is the MCF required?

    • 1. Vanishing Inc. Magic responds: The gimmick is made for a card folded twice. A MCF can be used
  • George asks: Do you have to use a style 808 box (which are getting hader to find) or would it work with an 807 as well?

    • 1. Vanishing Inc. Magic responds: You can use any bicycle box
  • Jim asks: I use a protective plastic case over all my card boxes. The card box slides into the case and the card box is used while in the plastic case. Will the gimmick work with this setup? Thx

    • 1. Vanishing Inc. Magic responds: That's fine because the gimmick lives inside the actual card box.
  • Christoph asks: Does the gimmick come in blue bicycle back design as well?

    • 1. Vanishing Inc. Magic responds: Yes, you can choose on the product page
