Review (2/5): Just Meh
The bristles are super soft, almost like a make-up brush soft. Too soft to clean anything. They were a light gray and got lighter after first use. 6 bristles fell out during first use. I doubt these have any charcoal compared to the deep, black coloring of other brushes.
The toothpaste is an unknown brand from China. I'll try many things, but I ain't trying that.
