A great switch that you will definitely use.

Soo cool and easy to master.

This fooled me the first time I watched this! I love how simple this is! Brilliant!!

Great trick and easy to learn

This is a ridiculously simple switch that requires very little, if any, practice. You do need to find or create a double-sided tuck case (a method for creating one is shown). For personal reasons, though, I never wear a watch, so I'd have to use a different misdirection technique, but that's just me and for most people, this is not an issue. Definitely worth having in one's arsenal of moves.

I like the Freeness of your offering. I have been using a double sided card box for many years. My handling is only a little different. After loading the unknown card, as shown in the video, I just turn over my wrist and set the card box down. It is very natural. If you feel like you have to, you can put something across the box, but I feel like it is better not to call any more attention to it.

Really nice trick + its FREE!

Very interesting and powerful idea! Definitely needs misdirection though.

The amazing trick with a tuck box, Love that it's free!

Simple yet powerful trick. Your way of misdirection is in my opinion very original and deceiving. The only problem I have with the trick is the existence of visual requirements from the tuck-case design, but you came up with a great and easy solution. By the way, I think you can even just use a regular case wrapped in cellophane (whether or not it matches the visual requirements). With the right amount of misdirection and time-lapse, I believe the audience won't notice the change in the case's orientation Thanks for the trick, Kaan!

A really cool switch that can be used in almost ANY environment. What's more, it's free.

Awesome trick, easy to learn..impressive. Thanks.

Free, well-taught & perfect for any level performer. I’m sure professionals can add some of their own flair but on its own, this effect is simple and effective :)

Simply amazing. Great trick that fools each and every time, and always love that it's free.

Simple. Brilliant. Fooling.

Just thank you, Kaan!
