excellent! hard to find...
like others, I always used woven floss, works much much better then flat tape... but, it was no longer made. then I found Dr Tungs and am on my second order of 6, is excellent, no more tape!
I had used Woven Floss for years and they just stop making it. I didn't think I would find something as close to it. I bought DrTungs Smart Floss and have been pleasently suprised. This Floss is even better with no seperation of the floss. 5 Stars all the way.
