I shave in the shower but I am going to have to stop. I keep missing places plus the whiskers tend to flatten. I’ll just buy a brush and shaving soap and give that a try. I used to do it but I broke the mug.
Go to Bed Bath & Beyond and get a small ceramic bowl that's used for making creme brulee, they cost about three bucks and work just fine.
I found a cheap coffee cup at Dollar Store that I used thirty five years ago. Fits a piece of shaving soap perfectly.
Now I shave in the shower and don’t even use it. I don’t need a mirror.
