Remember Silly Putty? This is the next generation.This stuff glows like nothing I have ever seen. It just sucks up the sunlight and brilliantly radiates it back to you. In the light it is ghostly pale and in the dark it’s a radioactive green. Great fun day or night.

A firm but smooth putty that's good for relieving stress and unlocking inner creativity. Stretch, roll, shape, tear, mold, bounce and squeeze this malleable substance to work out your stress. Not only is Glux good for hands and minds, its luminous properties make it fun for the eyes. Expose the putty to bright light and it will glow in the dark for hours. Made in USA
