Review on 4-Pack of Biodegradable Eco-Friendly Natural Bamboo Charcoal Toothbrushes for Sustainable Oral Care by Cara Ulfass

I was very hesitant to order this as I wasn't sure about the charcoal but I really like it. The bristles hold up much better than my other bamboo toothbrush I bought from Target. They seem to be doing a good job of keeping my teeth white. The only issue I had was that I lost a few loose bristles the first time I used it and it was quite frustrating to have them dangling in my mouth. My suggestion: run your finger over it before use to remove loose bristles. I only lost about 3 when I first used the brush and haven't had any issues since.
