I was wondering if that can dmg the brush because the inside looks rough.?lots of brushes and razors to choose from, but there does'nt seem to be a lot of choice when it comes to shaving bowls of a decent size,plenty of the mass produced ones on the various sales sites, but not ones that particularly appeal to me, i like some i see on Etsy, in fact i bought my black hand made one from Etsy, and i have another that i really like saved in my basket, have any of you guys got any good shaving bowls(not from the mass produced range) but something unusual and different
