This is a Brainwave Deck. It's made in Ohio and is of good quality. Also, the box has blue backs, but if you want to reveal a red card, this design is more natural. Poker size (An English instruction manual is included, but there is no Japanese instruction manual. For those who know how to use it. It's useful to always have it in your bag.) ★ The deck has been processed and set up after opening, so the product is new, but the deck case has been opened once. ★ What is a Brainwave Deck? It's a trick where the card the spectator freely thinks of is predicted. With the red-backed (or blue-backed) deck face down, spread the deck, and there will be only one face-up card. That card is the one the spectator was just thinking of. Furthermore, if you look at the back of that card, it will be a different color, proving the prediction. ★ Similar to the Invisible Deck, but the "Brainwave Deck" is more amazing.
