This little box contains a chunk of easily-chiseled material that contains a few parts of a small (2″)glow-in-the-dark triceratops or T.rex. Order one and take your chances on what kind of dinosaur you get. Order two and we’ll make sure you have one of each kind. Order more and we’ll try and make it evenly proportioned. These kits come with a chisel (okay…a little pointed stick) and a brush to clean your fossil. It says “Ages 7 & above” on the box, but I think that’s being overly cautious. There’s nothing remotely dangerous about any of the kit, except the small stick with the pointed end. I’d put the recommended ages at 4 & up.
