If you haven’t used an alum block…
I have never used an alum block when shaving, I recently made the switch to de razors and decided to get everything along with it. The alum block is a definite improvement to my shaving routine and it closes off the skin at any points where I cut or nick myself, its been 3 months of almost daily shaving and it’s barely worn down. I’ll definitely be buying another as soon as I need to.
