Stained my teeth!
Bought these to "go green" instead of using plastic toothbrushes. The standard brush in this pack is ok but the bristles are very firm, & the black bristle brush STAINED MY TEETH! I tried a different toothbrush & it removed a good amount of the staining, thank goodness. This is one of the more affordable bamboo brushes I've found on the market but you get what you pay for.
