Transpo box is a fun device that swaps signed cards in different places.

Effect:
The Spectator chooses two cards and signs them. The magician puts first card in the box and the second goes under it. With a wave of the hand the cards visually swap places!

Gimmick is very easy to make and the effect is stunning. You can perform the trick in person or on social media.
