The Pop Top measures approximately 6" long x 6" wide x 1/4" deep. It is made of a food safe thin plastic material and is one sided. It is very colorful. You simply lay it ontop your own cake. It is referred to as a Pop Top, as it has a 2D effect and appears to Pop off your cake. Much easier to use than the edible cake images as this is goof proof, and the child can have it to use after the party.
