This incredible crystal clear putty looks like glass, feels like dough, and melts like ice! You can you knead, mold, twist, stretch, snap, bounce and melt this malleable goo, and marvel at its uncanny translucence! However, the putty is thankfully unlike glass in that, once the putty is clouded fingerprints, simply allow it to rest and watch it return to its clear and unmarred state! 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.
