Shimmery white leads to rivers of iridescent purple, pink, and turquoise in Northern Lights Thinking Putty. Originally only found in local specialty stores, it's now available to anyone who wants to experience this magical display of light for themselves.
Charge it up with our Blacklight Keychain, darken the lights, and enjoy its ethereal sky blue glow...just like its namesake!
Milky white in daylight, their glow magically appears when the lights dim. In the dark, you can use our Blacklight Keychain to write messages on the putty and draw special designs. You can even do cool tricks with Glow in the Dark Thinking Putty. After exposure to light (the brighter, the better), these colors will glow for hours.
Made in the USA.
Each metal tin is hand packed with 1/5 lb of Thinking Putty, much more than you get in a plastic egg!
