Say hello to the cutest critters with the Gemini Peek-A-Boo Stamp and Die Collection! Each of the Peek-A-Boo sets has a number of stamps and dies to help you add curious characters to the front and interiors of your cards. This concept has been designed to help you add the front of a character peeking over the edge of a window on the front of a card, and the back of the character on the interior. This gives a fun peek-a-boo effect that your recipients will love! Just pair up the sets up with the Window Arches Die, which has been specifically created to be used with the Peek-A-Boo Stamp and Dies!
