This Review Title is Great but big mouth piece and the content is: Awesome brushes work good and fit my transition to zero waste. Super easy to cut down too for backpacking and use the kids size for my dogs teeth. The mouth piece is a little big so after this first adult brush So I think I’ll start getting just children’s packs cause they’re perfect size for my mouth and my dog..There are other information for this review, one is This reviewer did purchase it and the other is 0 people think this review is helpful.
