GLUX Putty is inert, non-toxic, and safe. GLUX Putty contains no latex or wheat compounds. It is safe for use by people with sensitivity to wheat or latex and will not promote the development of latex allergies.
GLUX Putty and many other silicone rubber products were developed during World War II as American industries searched for rubber substitutes that could be used in place of natural rubber tires, gaskets, and seals. Although it ended up having had no industrial use, it was kept around for a nifty toy!
