Not bad, just a disappointment. [SEP] I ordered this box of toothbrush is expecting all of them to be activated charcoal bristles. I really truly enjoy the activated charcoal tooth brushes. They seem to whiten and bright and very well. However, we don’t change our toothbrushes all the time and so I went to open it today and surprise! The toothbrush was not activated charcoal. It was just a plain bamboo natural bristle brush. Not that that’s a bad thing, it was just disappointing.
