Used by barbers since time immemorial, alum stone has been a mainstay of traditional shaving and men’s grooming in general. Alum is a mineral that soothes and heals. Just dampen it with cold water and run it gently over the shaved areas to close the pores and soothe razor burn. The Captain Fawcett Alum Stone Bag can also be used as a deodorant! A nice little canvas bag provided.
