The Osma Alum Block stops the bleeding of minor cuts during the shaving process, making it a great tool for men very new to shaving. It can also be used to prepare the skin before shaving.
Alum is a natural mineral revered for its ability to soothe shaving irritation and stop nicks and cuts from bleeding. A single block lasts for months and should be part of every wet shaver's kit, especially if you're new to double edge shaving. This can also be used as an astringent for those with normal to oily skin.
To use, rub the block on desired areas or any area where minor cuts have happened.
