The file comes with the 3D paper eggs and their mats, the holder base, the insert, handle pieces, and the holder base mats! The holder is approximately 3-1/2" x 6-3/4" x 3-1/4" and is compatible with both the 8x12 and 12x12 mats. The eggs can be filled with candy or money before you finish assembly then the recipient can simply press pinch the middle and bottom of the egg together to remove the items from the egg sides! As sized for the box, each egg is approximately 3" x 1-1/2" x 1-1/2" when assembled.
