These are a step in the right direction. I have yet to find interdental brushes with natural bristles, and in this case they are nylon bristles- but the bamboo shaft deffo is an improvement from a hunk of plastic. Does what it should, pretty durable for multiple uses.
Company did a great job in supplying my dental health products, prompt service, good prices.
Great replacement for the plastic ones which are so harmful to the environment. I purchased size 1 which I feel is slightly too large. Will definitely purchase again but size 2. Fabulous shop as well. Lovely customer service. Keep up the good work
