I love bamboo toothbrushes. Can't say it enough!I love knowing that I'm not putting chemicals into my kid's mouths every single time that they brush their teeth. We already use either a homemade toothpaste or an organic toothpaste. So knowing that I am not putting microplastics into their mouths every time they brush their teeth on top of using a great toothpaste is definitely a good feeling for me as a mom.These are well built, the Brussels are nicely attached. We don't have any issues with the bristles falling out.My only complaint is these are a little bit too big for my 2-year-old's mouth. I ended up going back on Amazon and purchasing smaller toothbrushes for him. If these were about half an inch shorter, they would be great for all ages of children. I definitely don't recommend them for a toddler aged child, but for my 5-year-old, 8-year-old, and 10 year old, these are absolutely perfect.I feel like they work great. I like that they are soft. I've heard a lot about the hard bristles on toothbrushes causing damage to your gums. So I switched us all to the softer toothbrushes. These are nice and soft they feel good on your teeth.These rinse out nicely, you end up with a clean toothbrush without a bunch of residue under the bristles. Sometimes they pack the bristles too tightly and you really can't get it clean in there, that was a problem that I had with the plastic toothbrushes. If you can't clean out the old toothpaste, how are you cleaning your teeth when you put it back in your mouth later. These are spaced well enough that you can rinse right down to the wood. I love the wood handles. Very pretty, and functional.Overall this is a definitely great buy. I will not be purchasing it for toddler aged children, but for my bigger kids I definitely will be purchasing from the seller again. The price point for the amount of toothbrushes that you are getting is fantastic!
