Volcanic Explosions—The key to Tstone’s effectiveness.
Tephra, a very close cousin to pumice, is a solid material explosively ejected from all volcanic eruptions. Grinding Tephra into a powder transforms it into semi-smooth “to-the-touch” texture, much like 1000 grit sandpaper. We form Tephra into the stone on top of the Tstone, so it can be comfortably rubbed on the skin. The Tstone delicately grips and lifts the hair and exfoliates the skin eliminating in-grown hairs and consequently razor bumps.
