Osma Alum Block, 75g

This was my first purchase of an alum block and love it. Cannot recommend it high enough.

I used cheaper alum blocks and they seem to leave crumbles on the skin, this is a very hard block that lasts a long time and leaves a smooth film

Brilliant product and a must-have for all shavers. It helps stop nicks but really calms the skin down after a shave (I use it after my head shave). Lasts a long time too so great for the price. Completely natural too.

If razor burn is a problem for you - it was for me - this is highly recommended. Sharp without stinging, application right after the shave and prior to any moisturiser really helps is reducing the redness. Can go a ways to stopping some small nicks, too.

I have no idea if this is effective or not, but it's been part of my routine since I started wet shaving. It's expensive, but it lasts a long time. I haven't had one crumble on me yet which I've read can be an issue with other brands.

This product is fantastic. It's a must-have product for wet shaving and will last a long time.

A quick rub of this over my noggin after shaving my head, no itches etc all little nicks disappear, and handles the occasional big slip with ease. I have found it much better than Styptic products

A must have!
Excellent for stopping little shave cuts.

If you have a razor, cream or soap and a brush, this is the next thing you need in your kit. I have used mine around four days a week for ten months and I'm only half way through it. Especially rewarding for beginners, it lets you know when and where you haven't taken enough care and paired with a good aftershave it can rescue all but the worst shaves. Your face will thank you.

Alum. Stings like hell if you shave wrong, freshens you up if you shave right. This block is massively overpriced. It's extremely cheap stuff if you find the right brand (or go brandless). Don't lick it.

A definite must have for any scrapes or cuts. It stings a little on ares of broken or stressed skin, which gives you feedback on how good your shave was. I found it a good size, and no crystal build up etc noted yet. A little pricey for an alum block.

What can I say? This product is absolutely fantastic. It's a must-have product for wet shaving. The Alum block will last for months, it cuts nicks and razor cuts and it doesn't leave any residue when compared to the styptic gels. Extremely useful post shave product.

This is a must. No matter how you shave or what you use, you need this product. That's it, no question. Instantly stops bleeds and closes pores.
Don't know how I got by without it and never going without it again.

This is a must buy if you're learning safety or straight razors. Stops the bleeding entirely in one minute flat. It also is great for giving you feedback on how well (or bad) you're shaving.

I purchased the Alum block to stop with razor rash and have found it to be successful in eliminating the rash. It also stops any bleeding from any small cuts that I may make.

This is the only Alum block I've used, so cannot compare to other products, but it will definitely remain a staple of my shaving routine.

Plus one for all other comments below : good for soothing that rosy cheek after an overly robust pass - my slight rosacea is now a thing of the past and yep love that tingling !

I purchased this with my DE kit. I knew I'd get a couple of nicks, and this did exactly the job it's suppose to; stop bleeding. In about a minute, after very minimal stinging I was not bleeding anymore, and the stinging felt weirdly enjoyable...

I wish someone had told me about this stuff when i was a teenager. can't imagine shaving without it now.
does tend to leave a residue if not rinsed off, i use it after shaving, before skin food.

even though i am a pretty careful shaver, alum is a staple in my routine these days. it doesn't sting for too long and the tingle is pleasant. it really covers or seals the skin. after a minute or so i rinse my face and apply some proraso pre/post cream. the block is 'thick matchstick box' size so should last forever. i'm more likely to drop and smash it before it runs out.

I love the feel of this on the skin straight after a good shave.
The slight tingling and feel reassures you that you have had a smooth shave,( you can feel if you have not), and the antiseptic properties are very reassuring.
I use this after my shave, followed by Thayers Witch Hazel and Geo F Trumpers skin food.

I've used this on small cuts & it stops the bleeding pretty quickly. Also the next day there's no noticeable sign that I cut myself there. Love it.

love this product, was a bit skeptical at first but since using it my shavers rash has disappeared completely, not even a hint of it left.

This is a great value product in my opinion. This small block will last you easily a year (in my experience anyway).

Its a means of both providing you with "Feedback" on your shaving technique (ie. if your pressing too hard during the shave, you'll know about it!), but it also provides you with a nice skin toning.

It also doubles are stopping small cuts and nicks.

Overall I think an Osma block should be part of every wet shavers kit.

Thanks again Mens Biz for offering another great product.

I had watched a number of YouTube videos which showed how this product is useful for treating small nicks and cuts. That is an understatement to say the least.

This product is the most important part of my post shave routine. When you've shaved correctly, it applies with a slight tingle. When you've pressed too hard and irritated the skin, this block may as well be made of fire. It's a really brutish but incredibly effective way of inspecting the quality of your shave. But perhaps most importantly, applying this block seals the skin after its blade encounter. For me, it has eliminated ingrown hairs, pimples and razor bumps to the extent that I can now shave everyday if I want, compared to no more than once every three/four days back in my Mach III days.

It's uncanny how useful this product is, particularly if you have sensitive skin and are prone to nasties like ingrown hairs and razor bumps.

Such a clever product - as someone who shaves head and face I quite often have a bleeding head (particularly when hungover).

This block helps close the wounds quick-smart!

Good at stopping nicks and cuts, dries out skin a little but nothing too much.

This product sealed the weepers I had pretty much instantly so it was extremely difficult to tell that I had cut myself. Additionally it doesn't leave any white residue which is great.

Got this after watching geofatboy on youtube (great videos on razors and shaving etc.) Really glad I got it, you can feel it sealing your skin after shaving leaving it feeling tight and refreshed.

When I use this on my whole face, it tends to dry the skin out a lot, even after washing off and applying a moisturiser so I only use it on small nicks and cuts now. Works great and will last a very long time!

There's no need to get any other block.
This one will last you a very very long time and it does the job as well as I had hoped.

Highly recommended!

I am a fairly new DE shaver and am happy I made the shift from disposables. This product really topped off the experience. I run it over the shaved area after a cold water rinse and leave on as I clean up. I then splash cold water on again, before after shave and moisturiser. I have lost the winter dry skin in just a few days and my face is smoother and feels great! Love it!
