Today, while I was brushing my teeth for the second time, the bristles came off from the top part of the toothbrush. They detached from the wood. It is not suitable for long-term use. It needs to be replaced quickly.

All the comments are very accurate and I bought it solely because it is bamboo, but it had rashes that hurt. I bought it the day before yesterday and they improved it, and I enjoyed it because they ate the corners and now it's smooth. Be careful to get the new ones!!! In the photo on the right, it seems that it doesn't have corners like the old one on the left, I hope I helped. I bought it from a supermarket!

I bought it because I found it on sale at the supermarket. Two stars for the simple reason that it hurts the inside of my cheeks. From the very first time I used it, it caused wounds on both sides of my cheeks, most likely because it is not waxed. Compared to other bamboo toothbrushes I have used, it is much inferior.

It does not easily reach the back teeth and it feels somewhat bulky. I am slightly bothered by the sensation of bamboo in my mouth. It is the first toothbrush with a bamboo handle that I have tried and I am trying to adjust.

Of all the bamboo toothbrushes I have used, it is the only one that penetrates the teeth so well. The downside is that it is quite hard, to the point of causing pain, despite claiming to be soft. The handle is not waxed, so it is not as water-resistant.
