I have a few (830, SOC, Amici) Semogue brushes and they all work fine. Truth be told, I prefer Omega brushes but that is really a

This is a chart I found elsewhere which pretty much explains the differences among Semogue brushes. I found it helpful and interesting.

Boars are a really nice way to get into the whole wetshaving discipline. Not expensive really and they do a good job without a bunch of fanfare
