This is the Systema sponge floss I've been using lately. I used to use Oral-B floss, but a friend highly recommended the Systema sponge floss, so I bought it to try it out, and I've been using this product ever since.
They say that using dental floss is good for your teeth and gum health even after brushing, so I recommend you all give it a try.
