This is a heart stamper part for Double Cross. It allows you to secretly stamp a heart on the spectator's hand. The heart it produces is made to look exactly like it was drawn by hand. This is the heart stamper only - you must already own the Double Cross pen in order to use this gimmick. The size of the heart is approximately .28" x .28". You can choose BLACK (the original color - most popular) or RED if you own a red Double Cross.
