Thinking Putty Glow in the Dark - Northern Lights
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.
