- Product Name: Shrinking Card Case - Brand: Bicycle - Model: Rider Back Thank you for looking. I kept it at home without using it much. I believe it is in good condition. Please consider it if you don't mind that it is a used item. The magician takes out a deck of cards and lays them on the table. There are 52 cards on the table, but when you look at the magician's hands, the card case has shrunk. #CardMagic #MagicTrick
