First dental floss not hurting my gums!
Only learning to use dental floss and couldn't get to it, everything I used before was somehow sharp and painful on my gums. This one is the first I'm actually not afraid to use again! It gets kind of 'softer' in the mouth which makes huge difference for my sensitive and bleeding gums.
The packaging is also used as a holder for the floss, which I haven't realised and I threw the box out and was later surprised that there was nothing to keep it in and cut it with. It is there - just not very clear. Or maybe it was just me, being the beginner ;-)
