The floss combined with the little reusable glass tube it comes in is absolutely no less thorough than any floss I've used in the past. And, no more throwing out plastic floss and the case it comes in! A very environmentally friendly idea by Hubby.

It’s cotton, the container is recyclable, and it works well, even with teeth that are somewhat tight.

Love this stuff! Easy to refill and does a good job cleaning between teeth due to the fact that it is not over coated.
