Phantom UV Putty is an amazing moldable putty that changes color when exposed to ultraviolet light. Like any standard putty, you can mold, stretch, twist, sculpt, bounce, and tear Phantom UV Putty. But when you introduce the included UV keychain light, you can draw, write, and scribble bright designs directly onto the surface of the putty.
