The Sorcerer's Stone of shaving has been found. Natural alum, known for millennia as a highly beneficial healing mineral, is now available for use in your daily ablutions, no wizardry required. For over 50 years, French laboratory Osma has been guarding and defending the ancient wisdom of alum manufacturing, and to this day relies on hand-cutting and other traditional practices to keep their minerals pure. The magic of the alum stone is its ability to tighten tissues and reduce inflammation, which translates to a closer shave and less irritated skin for you. Whether you choose the stone itself or one of Osma's proprietary potions, which combine the mystical mineral with moisturizing shea butter, you'll be spellbound by the power of a totally natural shaving experience steeped in the wisdom of the ancients.
