OSYN

Only is an understatement

This is shown mostly as a card effect though it can also be used for mentalism with few adjustments, meaning that this is a versatile weapon in your arsenal. In addition there's a VERY nice little bonus feature that I won't give away but I will tell you makes this effect feel like a steal at the price! Highly highly recommended!

Literally the only switch you’ll need

This switch opens up a whole world of ideas for things you can do! From playing around with it, I really like its application for card to impossible location but its versatility is my favorite thing! When you get this, keep a notebook close by because ideas are sure to follow!

Silky smooth switch!

When I first saw this effect it looked amazing, and it looked difficult. So I was blown away with how easy the method is. Great trick!
