Thin, strong and doesn't shred.  Worth it!
I purchased this after I saw a review by a dentist that gave said it was the best floss.  I was skeptical but willing to try.  So far it's living up to the review!  It's thin to go easily between tight spaces, but strong and doesn't shred as much.  Other floss tend to snap in two when it catches on the edge of my crowns, but this floss didn't!  I ended up using less floss in total since I didn't have to keep getting more floss when it broke.  I also like the flavors.  I thought the chocolate flavor was weird until I tried it but ended up loving it.  Worth the price!
