Bamboo Interdental Brushes (Reusable-7 pack)

I bought this item because it offered sustainable material (bamboo handles) as I was seeking to reduce the amount if plastic waste I was dumping into landfills. This earned the product one star. I expected the product to be reusable but it proved to be totally lacking in durability. Its brush broke and did not even serve one single complete cleaning of my teeth. How disappointing. The product turned out to be a total waste of money.
