Just really good floss Just really good floss. The flavors aren’t too strong — it’s really the texture of the floss that appears so effective while not hurting me that keeps me coming back. I did enjoy the Apple Cinnamon flavor recently, though. My other fave is Sweet Pineapple. Every little bit to help make this habit more pleasant and easy to keep, the better. I’ve given a year’s supply of Cocofloss as a gift, no regrets. The packaging could be more eco-friendly — I hope they are working on that. The subscription system and the perks could be easier to navigate, as usual for such systems, but it’s not too bad and also generally not a big deal if you accidentally get some extra floss for the cabinet — this is a perfect low-stakes relatively inexpensive everyday thing to subscribe to.
