The crystal that lasts
Across Southeast Asia, a smooth crystal of mineral salt has been used for generations as a simple deodorant. It is natural potassium alum — a mineral salt that, dampened and rubbed on the skin, helps keep you fresh through the day. A single crystal can last a year or more, needs no packaging once you own it, and carries nothing but the mineral itself. Sann cuts and polishes the same crystal, so the old, zero-waste way is simple to keep.
