Liquid Glass Crystal Clear Thinking Putty Music Or - just use themJust like its name implies, Liquid Glass Thinking Putty is unlike anything you've ever seen. This crystal clear creation is so transparent that the tin often appears empty to the naked eye. Liquid Glass flows and moves differently than other Thinking Putty because of its unique formulation and will turn cloudy when handled. Put it back in the tin, close the lid, and it will be back to crystal clear in no time. Gender: unisex.
