40-Piece Hand Shaped, Hand Polished Basalt Stone Set

8 large stones (back, leg)
12 medium stones (hands, arms)
16 small stones (forehead, neck, face)

Hand-Shaped Basalt Stones: All stones in this set are iron-rich, therapeutic basalt stones that preserve heat well.  Every piece of this black volcanic rock is carefully and dexterously cut to the same shape in various sizes. Then, much more skillful labor is required to polish the stones to a perfection particularly suited to stone massage therapy.
