Its a cool concept. But its pretty flimsy. Its not good for street/close up magic. And the flip is pretty visible. You can also tell its multiple cards put together. The video teaches you to make your own too but it requires a lot of other tools to recreate it. You arent able to had out the card for examination either. Like i said, cool concept but not really made as good as it looks in the video. I wouldn’t recommend it.

Flap Card

Fun visual. Lots of possibilities. Not something that can be done up close and would not pass inspection, and sometimes the sound gives it away. Definitely something you'd have to switch or ditch after the effect. Functional and comes with additional materials for repairing or replacing.

Awesome technology

What a great visual change
