desertcart.com: Gentleman Jon 3.7 Ounce Alum Block in Plastic Case - Upgrade Your Shave - Soothing Aftershave Solution for Shaving Razor Burn Relief - Travel Friendly Durable Plastic Case Included, Aftershave for Men : Beauty & Personal Care

Review: Must-have for wetshaving, very soothing and lasts forever! - This stuff is great! I just recently started wetshaving with a double edge safety razor and at first I just used Witch Hazel and Clubman Pinaud aftershave lotion. I still use both of those but after being highly recommended to me by several people I picked this up as well. It is DEFINITELY worth it! Being a beginner I'm still learning the proper technique and I was getting some irritation and even some "razor bumps". The witch hazel and aftershave helped a bit, as well as some facial moisturizer, but adding the Alum block to my regiment helped a LOT today! I just received it and tried it after shaving today and instantly felt a difference. I was told it also lets you know how you are shaving, if you rub it on your face afterwards and you feel some slight burning it means you weren't using good technique and you should adjust your angle and pressure. I did pretty well today with my DE razor and didn't feel any burning so that's good! I did have one small nick on my chin and it stopped the bleeding instantly. Before I recieved this the past couple shaves left my face very irritated and dry, even some dry skin peeling off in places. It's now been about 7 hours since my last shave using this and my face feels super soft and smooth with zero irritation. I'm sold! Everything I was told about this stuff is true so far, it is great! Just wet the block and rub it on your face, it soothes the razor burn and will stop any bleeding almost instantly in case you nicked yourself. I have a Clubman styptic pencil as well for cuts but this stuff works just as well and doesn't burn quite as much, plus you can use this stuff all over your face instead of just for cuts/nicks. The styptic pencil is also white and leaves a white residue on your face while this is clear and not noticeable. From what I've read these things last for YEARS. You just rub the block and barely use any, so paying the $8 is a good investment. There was a slightly cheaper and smaller block here on desertcart but it did not have a case. I'm kind of a neat freak and I like everything organized so the case is totally worth it! The Razorock brand Alum block has a case as well but it is more expensive and is only 3.2oz vs the 3.7oz this one is. Based on my research this is the best deal here on desertcart for an Alum block with case, plus the Gentleman Jon artwork/logo is really cool! I'm a huge fan of the vintage/retro styling. I've also read some people use this as a natural deodorant, I may try that in the future because I'm trying to be healthier and reduce the amount of chemicals in products I use. Since I'm using this one on my face though I'm gonna have to get a second one for that purpose, I wouldn't want to use this on my armpits and then on my face hah! TL;DR: Great quality, great case, great results, great value. If you get skin irritation from shaving, start using this after shaving!
Review: Great and refreshing way to finish your shaving routine - I am fairly new to wet shaving with double edged safety razors. I recently decided to up my game and bought a number of new items to add to my shaving routine; this was one of them. Along with a decent safety razor, shaving brush, shaving cream, and a bowl for building lather, this product complements it all perfectly. I tried this product for the first time today after a two pass shave with a Merkur safety razor and Proraso rinfrescante shaving cream. I could feel it working and absorbing into my skin. I had some minor irritation on my neck from shaving against the grain, but using this block soothed the burning immediately. I also had one small nick which the block took care of too. I originally thought this product wouldn’t be of much use to me. I would normally just rinse with water and apply aftershave. I’m glad I bought his product and will continue to use it every time I shave. It’s a really nice way to finish off a close shave and it feels good too.

## Questions & Answers

**Q: Where is the Alum sourced from, and here is the block made?**
A: Made in China. It's a poor quality alum block. I threw it away and purchased an Osma alum block which is made in France.

**Q: does this help prevent shaving bumps from ingrown hair ???**
A: Hello Anthony - Yes this is one of the main benefits of alum block.  The astringent properties not only stop bleeding, but for many people will subdue the irritations that cause razor bumps/razor burn.

**Q: Is it recommended to use this product without an aftershave? If not, should this product be used and allowed to dry before the aftershave is applied?**
A: It has no scent. So, if you want to smell good, use an after shave. If you dont, I suppose you could use it just fine by itself. This does not affect it's styptic abilities. However, there is plenty to be said about the benefits of using it with an aftershave, especially an alcohol based after shave. I highly suggest you use an aftershave with it, but you dont have to.I let it dry, and then apply a splash-on after shave. This helps remove any residue that some claim all alum blocs leave behind (though I have had no residue with this product).

**Q: Does anyone use this with witch hazel? How is the combination?**
A: I use this product in combination with witch hazel with no ill effects. The alum stops bleeding from any nicks but can leave my face a bit dry.  The witch hazel (I use Thayer's) contains aloe and restores moisture without any greasy buildup you often find with other products.

### ⭐⭐⭐⭐⭐ Great multi-use alum bar!
*by J***X on October 16, 2025*

Quick shipping and well protected so block wasn't broken or shattered in transport. The small translucent case protects the block when not in use. This block is not just for shaving or small cuts/scrapes but is antisceptic. If you wet the bar or leave your underarms wet after a shower, rub the bar well in the armpit area, then pat the block with a towel or piece of toiler paper and allow to dry in the case for the next use. When your arms air-dry the alum acts as a natural anti-perspirant and odor killer. I'll be re-ordering in a few months when the bar finally melts away...Great product!
