Osma Alum Block 75g

Strong…

A tiny block (compared to others brands I’ve purchased) but much more concentrated than those. It does a good job of closing weepers and certainly gives you feedback when you’ve been a little too aggressive.

Gives Accurate Feedback

I recommend an alum block over an alcohol-based splash for feedback. Alcohol splashes will burn regardless of whether or not there's irritation. An alum block stings and will only do so if you make mistakes. This block is very tiny. About 2" in length, and about 1" thick. Just a word of warning. The listed weight doesn't give a good idea of it's size.
