The Magic Eraser of Razor Burn!
Someone recommended an alum block to me when I started wet shaving with a double edge razor. I picked the Osma block after reading reviews and balancing it with the price. This product had good reviews and seemed like the best bang for the buck so to speak. I was a little surprised when they came by how small they are but I have been using one every day for a couple weeks now with no noticeable wear on it so a little goes a long way/they last a long time. They appear to be a solid rock crystal cut into a block. I am told that if you drop them, they will shatter. Some brands are not solid but rather the mineral dust compressed into a block using filler materials. I should also mention that two come to a package. This block does two things that I notice. First of all, it reduces/soothes razor burn. Secondly, if you nick yourself, this stops the bleeding (at least on minor nicks, I have not seriously cut myself since I have been using the Osma block). I should note that it does sting or tingle a little bit at contact on sensitive areas or areas susceptible to razor burn (under my jaw and on my neck for me) but the sensation fades quickly and leaves a refreshing feel. Overall, I would recommend this to anyone.

A must have if you shave! Wonderful product!
A MUST after shaving. Tightens the skin and will stop bleeding from a nick or cut. Don't wast your money on a styptic pencil as IMO this will do the same thing but will also tone your face and just give a great feeling right after your shave. Warning if you are new to DE shaving and not doing it right this product will tell you as it will burn but at the same time no pain no gain as it is the BEST product around for razor burn. I simply cannot live without this product. I use it with or without traditional aftershave but given a choice I would turn my back on aftershave completely as this block is simply incredible as is a must for anyone that shaves! I find a get about 6 months to a years out of each block. If you drop it its gone and will shatter so the 2 pk as a backup. One of the better values I have ever found in many years. A must have!

The best alum bar for the money
For gents out there looking for the quality of the Art of Shaving alum bar at half the price, this is it. Unlike cheaper alum bars, this one will not disintegrate after a few uses - it holds its smooth bar shape until it gets used up or you drop it, in which case it can and probably will shatter or break. Just dry it after use - if you don't, then it will get crusty on the bottom. As long as you do that, it will last for a LONG time. I shave twice a week and one bar lasts about 6 months, so approximately 100 shaves. For gents who do not use an alum bar, you should. Yes, it stings, but it gives you feedback about where you're being too aggressive with your shave, and it makes your skin tight and helps seal up any nicks, prevent razor rash, etc.

I mean anyone who knows anything about shaving knows that these are magic!
I mean these things are pretty magic, they do exactly that they are suppose to do and will last pretty much untill the end of time. How come nobody tells you these exist? i spent most of my teens tearing up my face and dealing with razor burn needlessly! This product is something you HAVE to have if you shave on a regular basis. Overall this thing has changed my shaving life and i love them. And i will definitely buy these again in the future if i needed to, but unless someone steals mine i think they will probably outlast me even if i use them every day.

Must have for straight razor or DE shaving
Alum blocks are used as an aftershave product to help your skin recover from being scraped with a very sharp blade. If you shave with a double edged or in particular a straight razor, an alum block is a must have in your shaving kit. (For more info on shaving and related products, see my reviews of the "Feather Hi-Stainless Platimum Double Edge Razor Blades 50 Ct", "Norton 24336 Japanese-Style Combination Waterstone 4000/8000 Grit", and "Green Chrome Oxide Compound, 6 oz".) SOME RECOMMENDATIONS ON USE If you're into wet shaving and have an internet connection, you've no doubt discovered that there are many varying opinions on the ideal selection and sequence of shaving products that will lead to a superior shave. Almost each of these magic formulas will tell you that they have discovered THE BEST WAY to shave. People try them out because they are always looking for a way to up their shaving game. For me, after trying a lot of approaches and spending way more than I should have on different products, I've come back to the basics. The alum block is a key post-shave step because it helps to disinfect the surface of your skin, where there may be various microscopic (or not so microscopic) cuts in the skin; it stops bleeding; and it tightens up the skin, leaving you with a cool and fresh feeling. Unlike other reviewers, I don't leave the alum on my skin after applying it, because I find it dries out my skin and feels overly tight and uncomfortable. After my shave, I rinse my face with cold water, apply alum everywhere (and yes it will sting in places where your skin has been irritated or cut), let it sit while I brush my teeth, then rinse with cold water and pat dry. Then I apply some kind of moisturizer; I'm not a snob about it and I usually just put on whatever my wife happens to have around. PROTIP #1: alum may be great for your skin but it is corrosive to metal, including the shiny new shaving tools you've just bought. Store the alum separately from anything metal, don't let it come into contact, and don't use your razor to touch up any unshaved spots of your face after you've applied the alum -- make sure to rinse it off first. PROTIP #2: alum blocks are crystals and are very fragile. If you drop them, they will shatter. This doesn't make them unusable -- the entire thing is made of the same chemical compound -- but the sharp edges make it rather uncomfortable. I hope this little mini-dissertation on alum blocks has been useful. I've tried to offer a personal perspective that goes beyond "Great product; arrived on time" and I hope it will be helpful for some of the beginning shavers out there.

Game changer
Get this if you have sensitive skin and/or get razor burn. I have never been able to shave daily as I always get razor burn and irritation. My beard grows quickly so this ends up leaving me with stubble. I switched to a double edge razor which helped a ton, but this alum block has been a godsend. I can now shave daily without irritation. I would recommend washing your face after a min or so after using the alum block and then apply face lotion.

The best alum there.
Extremely good product. The blocks are perfect and last long (dry after use). Good quality. I use after my DE shave, it tells me if I have any nicks or burns (a feedback on my shaving) and also heals them. Wash off after a while and then apply your face cream etc.

Great product, damaged during shipping
A must have for anyone who uses a straight razor. Would give 5 stars but one block came broken into several pieces. Still usable just not as convenient. Donโt expect this to deal with major cuts. Try a styptic pencil for that.
