A card fits into an unopened plastic bottle. "The Card that Travels Through a Plastic Bottle" Please prepare a plastic bottle, masking tape, a paper bag, and playing cards. Includes Japanese explanation (DVD and instruction manual. Both are in Japanese) The plastic bottle caps are 20 in total: 10 plain white caps and 10 caps that say "open." There are a few more gimmicks without the DVD. This belonged to my father, and I tried it once. The cap is easier to open than a regular plastic bottle. It becomes unopened, but it's not as tight as a regular plastic bottle cap. #riina_magic
