Highlights

Take a Closer Look

This Alum block is a natural product which helps seal small nicks and cuts.
It acts as an astringent and can be used to tone the skin leaving it smooth and silky after shaving.
Simply wet the stone and rub on the affected area.

Not only does it aid in soothing skin irritation, but the properties in the Alum block ensure that the hairs on your face grow straight out from your face and neck, which prevents ingrown hairs.

- Pure Natural Potassium Alum
- 100gr Alum block

Made in China

Important note:
Don't use the alum block before wet-shaving.
Please do not use around eyes or sensitive areas.

Highly effective alum block that "really works" for post-shave care. Customers praise its ability to stop nicks and cuts, reduce razor burn, and calm skin. Some also use it as a natural deodorant with success. Minor feedback suggests it may be less concentrated than similar products, and some prefer a container for storage.

  • This alum block really works - especially good for sorting out nicks and cuts
  • Absolutely incredible. I use the stone as a natural deodorant and it works perfectly
  • Stops any nicks bleeding and seems to calm my skin

It works

I’m new to safety razor shaving but after doing some research and watching far too many (honestly) YouTube videos on the topic I took the plunge. This alum block really works - it has been especially good for sorting out the inevitable nicks and cuts as I am learning the technique of using my new Muhle R89 Twist.

Would happily buy again but might look for something in a container.

It is absolutely incredible. I use the stone as a natural deodorant and it works perfectly... Not bad odours at all. Quick delivery :)

Allume block

It's handier and easier to use than the round sticks but I feel it's not as concentrated as the Muhle Alum pen. Not sure if that's good or bad yet. Still, it does the job and I'm happy with it.

Found what I was looking for @ Fineshave

I am more happy to find fineshave than the product itself. The online purchase experience was very satisfactory. Prompt delivery and effective communication. Loved it. Will come back and refer it to friends.

The alum is good and effective.. have used it several times.
