Each kit includes five tins of clear putty, three concentrated color putties, three special effect putties, and an instructional mat—everything you’ll need to make cool Thinking Putty colors that are all your own! When the mixing is done, the fun’s just begun! Play with your new colors by day, and enjoy their awesome green glow by night.
