When thinking of traditional shaving techniques, few items are more evocative of such old World flair and expertise than the Osma Alum Block. It’s easy to see why; while alum blocks are classic items, they still possess the efficacy of many modern innovations, especially when it comes to soothing skin thanks to its antiseptic properties. Skin is left feeling cooled and calmed, with bleeding caused from shaving nicks brought to an immediate halt.

    Stops the bleeding but stings like Muhammad Ali.

    Bought the Alum Block after reading reviews on here and I must admit I was sceptical. However it really does work. Used it half a dozen times now and I’m very impressed. Looks like it will last for a very long time.

  4. Malcolm B.

    Excellent product would recommend.

  5. Mick R.

    Works a treat – the original and great however I prefer the Feret block due to its curved end and larger size, however that is significantly more expensive

    First impressions was the physical size, I thought it would be bigger, however on opening it I wondered how something that looked like quartzite would work, well you live and learn, on first use, the razor burn vanished, small bleeds healed, worth the price, just remember to rinse and thoroughly dry after use, highly recommend this product

  7. David C.

    Also a great deodoriser.

    I have used it a few consecutive times and am defiantly seeing a positive difference to my skin. It sorts out nicks and leave my skin smoother.

    Does as expected:
    – Stops bleeding
    – Stings to let you know about your technique
    – Hard wearing, plenty of use in the block
    – Tones the skin to help soothe after shaving

    I do like this block, its easy to use will last a very long time and pretty much does what it says it will do. Small nicks are dealt with easily although I still find myself using a tissue to stop the flow in larger cuts. Nice and easy company to deal with though.

    does the job

  14. Cameron S.

    Does what it says on the tin, almost magical to have small nicks just stop bleeding.

  15. Tony

    Excellent product that does exactly what it’s meant to!!!

  16. Samu

    I was worried about the size, but it is perfect and the packing is classy as well. The product works like a charm and is a must for every shaver

    An alum block should be part of everyone’s post shave routine. This block is a great product. It leaves the face feeling tightened and refreshed. Don’t be put off by the size of this block, it’s a little bigger than a matchbox, which makes it perfect for following the contours of your face. I’ve used mine now every shave for a month and haven’t noticed any change in the block size. I’d guess it will easily last 12 months.

  18. Jan C.

    First time user, and really happy. As well as help your skin out, it’s a good indicator of how your razor set up and technique are going. This particular bloc is nicely packaged and good value. As ever superb service to keep me using these guys for everything I need. Thank you.

  19. James C.

    Everyone should use a block in their shaving routine best thing shaving product I’ve ever used!!

    Small block of Alum, works well for me. Finish a shave wash of the soap and run the block over the wet face. Closes off any nicks and red areas leaving a great finish to the face. I don’t know why it makes a difference but it does. recommended.
