Our explosion boxes are innovative and extremely popular for gifting on special occasions. It is a unique birthday gift. When closed, the box looks like a regular gift box measuring 4″ by 4″ by 4″ but when open, all the sides fall back to reveal a large 12″ by 12″ card with a thematic 3D element in the form of a cake slice in the center. The birthday explosion box contains 3 photo spaces and 2 pockets for message tags. You can also slip in a gift card, or cash gift. Note: As all items are handmade, minor variations from the product pictures may occur.
