PerfectSense Professional Hot Lava Shells are made from real Tiger Clam shells, which are modled and bonded into perfect massage tools. The shells are heated without the use of electricity by combining all-natural ingredients, such as kelp and Dead Sea salt, with the Lava Activator pouch. This sets off a mineral reaction that generats a heat that reaches between 120 and 125 degrees and lasts for about one hour.
