Every Lava Shell is a real, hand-selected Tiger Clam shell from the South Pacific. A part of the local diet for hundreds of years, the shells were previously thrown away, as the villagers had no use for them. But now, Spa Revolutions has taken these natural beauties and recycled them into a powerful tool that allows you to perform an entire heated massage with only one or two shells. Combining beauty, ease of use, power, and unparalleled versatility, Lava Shells are allowing spas and salons everywhere to incorporate heated massages into their services in revolutionary ways. Order seashells for home massage treatments for a perfect home relaxation experience.
