Here is a large, stylish and luxurious card box, elegantly made in mahogany wood with brass fittings. The inner size measures 121 x 190 mm.. 

But what can such a card box do, some might ask? The box can be used for the appearance tricks, disappearance and transformation of giant cards or other flat things - eg. a banknote, a ticket, a prediction, a flat envelope, etc. One of the most commonly used effects is:

A spectator draws a card that is then torn into several small pieces. One of the pieces is handed over to the spectator and the other placed in the box. The lid is closed and when it opens a moment after, the card has become complete again. Or rather, almost complete - because there is a corner missing. Here the spectator's piece fits perfectly.

There are several advantages:
1. There is a built-in magnetic lock in the wooden board, so the box can be examined after the transformation has occurred.
2. The box is made so that it can contain an entire deck of cards. So you can store your deck in the box and thus introduce it without your spectators thinking of a magic prop.
