This is a good floss. Not only does it move easily, between the teeth, it really does remove the stains that can develop, in between them. I've exclusively used Glide, for years, now, because it just makes it so easy to floss. Other brands can get stuck and shred, but Glide goes right through, without a problem, and stays in tact. I didn't have access to this whitening variety, for a few months, and the stains between my teeth came back. I started using it again, and within a couple of weeks, the stains are gone.
