Hi Bob, welcome to B&B.
The bristles in a bristle brush are boar hair.
[SIZE="1"]Ah... You can't beat the cold steel and the badger. All this electrical rubbish, little wheels spinning around all over the place for callow youths and peach fluff, Not for a man's beard. Razor blades for men! I think we'll have this on number 9. If you're going to have a shave have a close one!
