UV Reactive Putty

UV Reactive Putty reacts with vibrant colours to UV light. Shape the putty to however you want and then draw on the putty with the supplied keychain torch. Write things on it and over time it will disappear giving you a blank canvas. As with normal putty you can stretch, mould, or shape it.

Each metal tin is hand packed with 1/5 lb (90 grams) of Thinking Putty. You'll also find a small UV keychain torch in each tin.
