Ditch the harsh and irritating perfumes that just mask underarm odors and try a whole new concept in deodorant! Our new Mineral Salts Deodorant Stone goes on invisibly and prevents body odors from ever forming. No rash, no stains on your shirts, no toxic chemicals. Made from 100% potassium alum mineral salts, this all natural, non-toxic deodorant stone creates a thin film where odor-causing bacteria can't thrive. It also acts as a natural astringent that can be used like a styptic pencil to stop small shaving nicks. And it lasts and lasts – one 4.25 ounce Mineral Salts Stone will last about 2 years with normal use, saving you money.
