I purchased this on Mercari. I bought it, but I'm selling it because I haven't had a chance to use it. Thank you for looking. The following is the introduction comment from when I purchased it: ↓ This is a set sale of a Rainbow Deck + a prediction card that allows you to perform the Strun card trick devised by Renato Green. You can create the same effect as the magic performed by Takumi Takahashi on TV shows. This is a one-way deck made using 50 popular decks, with all different backs and all the same faces.
