Is it a kid's toy or a stress reliever for grownups? Either way, you can't put it down. Made in the USA, the tin is packed with 1/5lb of Thinking Putty. As white as fallen snow with translucent green and red sparkles, shine the included blacklight and white changes to a festive red.  But wait! Turn off the light and red magically transforms to glowing green. From Crazy Aaron's Thinking Putty, for ages 5-10 yrs.
