This is the best floss I've ever used. It's more comfortable to floss with the thicker floss. It does a better job in my humble opinion and isn't painful for the gums.

Love it!
I feel like I’ve had my teeth cleaned at the dentist every time I floss. Makes me want to floss just to see what I get out on that black thread. Thank you for a great product. I’ll def keep it in stock.
