Product Description

Osma Laboratories

Alum Block

The Osma Alum Block is a versatile and essential grooming accessory that has been trusted by men for generations. Crafted with meticulous attention to detail, this remarkable product offers a wide range of benefits for those seeking a high-quality shaving and skincare experience.

Made from premium-grade potassium alum, the Osma Alum Block is a natural mineral with remarkable properties that make it a must-have for any well-groomed gentleman.

Skin soothing Alum Block

It serves as an aftershave, antiseptic, and styptic agent, making it an all-in-one solution for various skincare needs.

One of the standout features of the Osma Alum Block is its ability to soothe and heal the skin after shaving. When applied to freshly shaved skin, it provides immediate relief by tightening the pores, reducing redness, and calming any potential irritation. This makes it particularly beneficial for individuals with sensitive or easily irritated skin.

Furthermore, the Osma Alum Block acts as a styptic agent, meaning it can effectively stop bleeding from minor cuts and nicks that may occur during shaving.

1

By simply moistening the block with water and gently applying it to the affected area, the alum creates a thin layer that coagulates the blood, aiding in the quick closure of the wound.

5.0 out of 5 stars Excellent Alum block + Tips for Beginners
Reviewed in Canada on February 8, 2024
I actually was surprised to see how small the alum was, in the pictures it looks massive. I took some measurements using a digital caliper. an put items for scale, a dove soap bar and a 2-dollar coin. While I'm sure the alum works well, I found a bigger one on fendrihan.ca, It is the same brand just a bigger bar this one is 2.65 ounces while the other one is 3.5 ounces, the dimensions approx. (2 5/8' x 1 5/8' x 7/8') (6.5 x 4 x 2.2 cm). It may be thinner, but it is also heavier, taller and it comes in a plastic box.

The bigger Alum is $17.50 Canadien, so it is more expensive, but you are getting a carrying box, so it is more costly. Well, it is up to you everyone this bar works just fine, but if you want one with a carrying case, I'd go with the Bigger one, or if you want more value for money go with this one.

Some tips:
- wet your face then apply alum block (It will make the alum last longer)
- Wipe the alum block with a towel and let it dry off (helps keep the shape uniform, and crystals will not form in the alum)
