Most commercial floss is made of petroleum-derived plastics such as polyester and nylon. Microplastics may remain between the teeth and accumulate in the body, or may leak into the sewage system during the use process, which puts a burden on both people and the planet. That's where 100% naturally-derived silk dental floss came in. Point 1.　Made from the finest natural silk Made from 100% of the finest natural silk. Not only is it derived from nature, but it is also easy to use because it is durable and hard to cut. Point 2.　Light and stylish bamboo case The case is made of FSC-certified organic bamboo, which is light and compact, making it easy to carry. When you're done using it, you can easily open it and replace it. (Floss only is sold separately.) Point 3.　Refreshing with mint flavor Because it has a natural mint flavor, it is refreshing and refreshing. Point 4.　100% naturally derived and returned to the soil The floss, case, and packaging are all made of naturally degradable material. It returns to the soil, so when you're done using it, you can put it in your compost at home. Comes with FSC certified bamboo case
