Smile! It’s good for the environment!
We love these. They work great. The only reason for the 4 stars is that a few of the brushes had some bristles that came out and got stuck between teeth when brushing. It is not an ongoing problem, it just happened with the initial use. So maybe just run water over them and run your finger back and forth before using in your mouth the first time. I would still recommend them for your smile and the environment!
