I’ve used this floss exclusively for a number of years now, but it seems to be getting harder to use without leaving some of it between my teeth. I've always liked its low cost, but more so, its resistant to shredding. It seems to getting less so though, and I've found it shreds quite easily now. I can't decide if this is a supplier issue or perhaps the specification has changed. Either way, I think I'll be looking for a new floss.
