Detailed Product Description"These 3D delights like to be called 3D Greeting Card Gifts. More than a greeting card, an Oh Wow! card is a startlingly realistic little 3D world--a unique gift (or souvenir) all its own. An Oh Wow! card can be mailed flat, like a normal card. It measures 5 3/4"" x 6 3/8"", and comes with a paper envelope. There is a space for writing messages on the back.
The card easily pops open to form a box, with a pair of lenses embedded on one side. Often, extra images elaborating on the card's theme enhance the side panels connecting the front and back of the box."
