Hours of fun are underway with Sol Putty! This unique, safe color-changing putty transforms from white to purple with sunlight.
For indoor fun, each putty container comes with Del Sol’s proprietary mini UV-LED light that lets you draw pictures, letters or whatever you imagine on the putty.
Our non-toxic, all-organic formula won’t stain and is water soluble. Everyone will love to see the magic unfold in the palms of their hands.
Don't forget to include this color-changing, tactile fun for all the good girls and boys on your Nice List!
Much like a flower that blooms when exposed to sunlight, Del Sol's products change colors in the sun using their proprietary Spectrachrome® technology.
Spectrachrome® molecules in the products shift to colors visible to the human eye when exposed to UV sunlight.
Del Sol's Spectrachrome® formula for color change was developed from a concept originally researched by NASA for use in space.
