Tenyo - 4D Printer

The magician slides three large blank cards into a window envelope.

Although the cards are clearly seen through the window as they enter the envelope, and although they never leave the audience's sight, the cards magically transform into playing cards. It looks like the cards were printed by real magic.

A clever gimmick that is hidden inside the thin envelope enables you to easily switch the cards while in full view of the audience. Although you can perform this effect one-on-one, the cards are large enough to be seen by larger groups at a party or other gathering.
