This incredible green glowing clear putty glows in the dark and shines when nothing else does! You can you knead, mold, twist, stretch, snap, bounce and melt this malleable goo, and marvel at its uncanny reaction to light and darkness! To activate the glow, your putty must first be exposed to bring light. Once you've given it a healthy dose of lumens, turn the lights out; it's putty time! Watch it glow with green brilliance. Unlike other putties, this one won't leave you with sticky 'resi-goo,' and no matter how much you play, the putty will never dry out! Includes a handy tin for storage. Makes an excellent holiday stocking stuffer or party favor, and can be used as a fidget toy to help children with special needs focus during class, or as a stress-reliever more generally.
