sponge dental floss

It is a sponge dental floss from No Brand.

I bought this casually as a substitute because I forgot to take it on a trip, but it works surprisingly well as a sponge, so I've been using it ever since. It even comes with an extra refill, so the value for money is excellent. Whenever I eat meat, I immediately reach for this floss. I use several types of floss, but this is the one I reach for whenever I eat something tough.
