Glow-in-the-dark plastic skeleton, about 1 ft. tall. That is the end result. What you get is a box of bones that you snap together to create the final product. Which is kind of fun. Or of course you can leave some or all of them disassembled to create a sense of havoc. We're not going to claim it is anatomically correct, or educational. But you do need to figure out that feet don't grow from shoulders and thigh bones do not connect to jaw bones. Maybe 5 minutes of fun!! And the finished product is one of our better little Halloween guys.
