Nice soft bristles
I didn't give this 5 stars because I'm skeptical about the "charcoal" in these toothbrushes, as they don't seem to emit any charcoal and it seems the bristles are really just black.  But, I am pleased with the bristles, they are nice and soft for hard teeth scrubbers such as myself, and it is a novelty to use a black-bristled toothbrush.  The handle is very nice as well, with a comfortable grip.  I will definitely buy these again, simply for the soft bristles and aesthetically pleasing colors.
Rating: 4 stars
