ESCAPE (Online Instructions) by SMagic Productions
ESCAPE - THE BEST CARD CORNER TRANSFER EFFECT
Smagic is proud to release ESCAPE. From the mind of Ninh, we know you will fall in love with this easy-to-perform, visual effect. 

The spectator selects any random card. Tear the corner and have them sign their name on it. To keep it safe, you place it inside the card box and close the lid -- they can see their signed corner inside the box. Place an envelope on top of the box. When you remove the envelope, the corner has DISAPPEARED from the box! Astoundingly, it travels and REAPPEARS INSIDE the envelope! Remove it and give it to the spectator. 

Truly a miracle - your spectator will be astonished when their SIGNED card corner is revealed. 

with detailed tutorial only, no props included

Check it out and enjoy performing ESCAPE!
