Review: 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. Review: 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! ### ⭐⭐⭐⭐⭐ This is a alum block not pressed together alum excellent quality productl *by M***C on May 15, 2018* I have tried many different Alum Blocks (they are not blocks they are pressed together, disolve and break very quickly) I like them until the start breaking apart, they tend to be very fragile and not because they were dropped, this is a solid block , I was actually ordering rollon bottles to use them for all the alum blocks that I could no longer use because the were so fragile, planning on grinding to powder and adding water to see how that worked, I saw Osama alum block and thought I would give it a try, extremely happy and suprised at the diference, I use it on my whole face, after shaving, as a deaodorant and on my feet, excellent product, perfect size will last longer because it is a solid block of alum, not pressed together alum, big difference and ther is no mildew issue getting in side solid block.
