This is a 7 of Spades stamper part for Double Cross. It allows you to secretly stamp a 7 of Spades on the spectator's hand. The 7 of Spades it produces is made to look exactly like it was drawn by hand. This is the 7 of Spades stamper only - you must already own the Double Cross pen in order to use this gimmick. The size of the stamp is approximately .28" x .28".
