Excellent flossing!
I love the way the floss really cleans my teeth and does not shred.  Plus it's biodegradable (vs. the standard nylon) and comes with a second refill.  The little glass bottle is about the size of my thumb (glass breaks down whereas plastic never does).  I plan to give this to my friends and family to spread the word (yet another way to reduce our dependence on plastic products!)
