10PCS/Pack Soft Bamboo Charcoal Nano Toothbrush Black Tooth Brush Dental Personal Teeth Care

Unfortunately they weren't as I expected. And in addition the package was open. The thin brushes bend even after one wash. Too bad

Better not to buy, it feels like it's only for children. It seems like the handle will break now, and the brush itself is small. I bought it in vain, it's like for one use, use it and throw it away or for travel and throw it away
