Just like its namesake, Quicksilver Thinking Putty® is a saturated silver color with dark streaks throughout.
Warning: Contains strong magnet. Swallowed magnetics can stick together across intestines causing serious infections and death. Seek immediate medical attention if magnet(s) are swallowed or inhaled.
PLEASE NOTE: While Quicksilver Thinking Putty is inspired by the element, it does not actually contain any mercury.
