Who would have thought that there was floss that was bad? I obsolutely despise this floss. I have teeth that are pretty tight together, making the gap between them very very minimal. I never thought twice about floss, but will be doing so now as this floss just doesn't get in between my teeth. I feel like I have to fight it. Not only does it take forever to hetbin between my teeth, it also separates. The floss becomes two seperate strings before I am even done flossing. I have used flosses that simply glide between the teeth with ease and this is not one of those floss. I do not recommend this.
