3 1/2 inch art toy made from CosClay (a rubberized polymer clay) over an aluminum armature. The teeth are hand sculpted with glow-in-the-dark CosClay. Spikes are tumbled Tiger's Eye. Its eyes are custom made from glass cabochons. Painted and sealed with acrylic paints and varnish. This is a one-of-a-kind art toy made for adults, not children. Ready to go on adventures with you, or to be displayed in your home. Be forewarned, these little creatures love attention. If they don't get it, you'll notice them glaring at you as you pass by!
