Sponge dental floss good for cleaning between teeth

It's No Brand sponge dental floss.

The floss isn't too thin; it has just the right thickness, so it fits the spacing between my teeth perfectly. I especially like that it's made of a sponge material. It seems to work on the principle that saliva gets into the sponge and expands as I floss. As the floss thickens, it allows me to remove debris from between my teeth more cleanly. Since it's a no-brand product, it's affordable, and it's better than expensive floss.
