Aftershave Blood Stopper Antiseptic Astringent Soothing Solution for Shaving Razor Burn Relief : desertcart.co.uk: Health & Personal Care Review: Essential feedback tool for wet shaving, and the case is a lifesaver - If you are new to safety razor shaving or just tired of using tiny toilet paper squares for nicks, this block is a substantial upgrade from standard styptic pencils. I was surprised by the sheer size of the 100g block; it is the size of a bar of soap and, given how little dissolves per use, I expect this to last me well over a year. The alum works exactly as intended, providing immediate feedback—meaning it stings briefly—on areas where I applied too much pressure, while instantly sealing up small weeping cuts and tightening the skin. The real selling point for me, however, is the included plastic case. Since alum is highly water-soluble, it will slowly dissolve into a mess if you leave it sitting directly on a wet countertop, so having a dedicated container to store it in is essential for keeping it clean and intact. My only word of caution is that natural alum is brittle like ceramic, so if you drop this on a tiled bathroom floor it will shatter, but as long as you keep a good grip, it is a fantastic finish to a shave.

Does the job & a good size ### ⭐⭐⭐⭐ Great product *by G***S on 22 October 2025* This is a great product stops any bleeding quickly, reduces the size of pores, it comes with a case to keep the product clean. The block appears to last a long time I’ve only had it two weeks and the size has not reduced too much. The product was delivered next day. This would have had 5 stars but the product does sting. You could say that’s my fault for cutting myself but I am using a cut throat razor. ## Frequently Bought Together - Jack Shaver® Natural Alum Block in Plastic Case (100 g./3.5 oz.)
