🧱 Bloc Osma Alum Stone - 75g Block (Pack of 3) Review

This is specifically advertised as Bloc Osma which is by far my favorite alum. This is a very cheap 7126 block of alum. It is of poor quality, a large corner of one block crumbled and fell apart when I unpacked the plastic (no box). This is absolutely false advertising. Do not buy from this seller.

Useful for checking skin condition after shaving. Unlike other similar products, it is not easily deformed when in contact with water.

Stupid but since the product is called Bloc Osma I thought I'd get Bloc Osma. Instead I got something called Dr. Sharp Barber Alum. I inserted an image. Also, it must have been shipped across the Pacific on a sampan as it took over a month to get here. Find someone else to buy Osma from.

I am a DE razor and have been using them since I started and they taught me how to shave. I have tried many other products but none compare to the Bloc Osma brand. This is my choice of alum and I would highly recommend it if you enjoy adding alum to your shaving routine. For this price it is difficult to find such a good deal online. I hope this review helps.

I've tried other alum blocks and Bloc Osma is much better. The surface texture is much smoother. It feels like the block is one solid piece rather than a bunch of small crystals bound together. Glides very easily on my skin. Was a little surprised how small the blocks are but still think they will last a long time.
