三明治互换

是一款三张相互呼应效果。魔术师左手拿着一张数字牌，右手握着两张人头牌。就在眼前瞬间相互调换位置。也可两位魔术师一起配合，这样看起来效果也更有趣味性。

道具角度易懂，无需高难度。

产品包括蓝背单车道具牌+中文视频教学。

Instant Transposition

The performer holds a number card in his left hand and two court cards in his right hand. They transpose in an instant. Or two performers work together to finish the routine that maybe more interesting.

All is performed visibly without any suspicious move.

Super easy and visual.

Comes with the prop and video instruction.
