Every year, Crazy Aaron's releases fun and festive Thinking Putty in seasonal and holiday colours. Available for a limited time only, these special editions come with varying effects and add-ons and are highly collectible.
HOWL is a glow putty and comes with a Glow Charger. It also comes with a moon transparency - use the Glow Charger to recreate the major lunar phases. Just lay it down over a flat circular shape of Howl Thinking Putty in a dark room to experience its amazing effects. Hold the Glow Charger about 15cm away from the putty.
