Great for the environment!

It's great, but would recommend if you have tight spaces between teeth, the best one would be, Peppermint w/coconut oil sponge floss. 🦷

Took a chance...

I purchased this floss without knowing quite what I'd be getting, primarily because I wanted a floss that didn't have any extra "stuff" added to it. It would be nice if Radius would add the quantity of floss to the listing; that's an attribute consumers generally like to know. I couldn't see an amount listed in the description, or visible in the photos, so for anyone who would like to know, one package includes 33 yards / 30 meters of floss.

I've been using this floss for about 3 weeks now. I've maybe broken the floss three or four times while flossing. This floss is a little different than what I'm used to, it feels a little thicker and has a little more resistance between the teeth. Overall, I like it and I'll continue to purchase it.

Really like it!

The Silk Floss seems to have more traction than the plastic flosses. I really like it. Furthermore, I totally appreciate that Silk Floss is manufactured without the inclusion of PFAS. Thanks so much.

Serious dental floss

This floss, aside from the marketing standpoint of being biodegradable and all that stuff that we're all in favor of, has three things going for it that distinguish it from the others. 1. It's unscented and unflavored. 2. It's at a good price point and 3. It has a coarse enough surface to really clean the tooth surface while also being very narrow which compensates for no waxiness or other ultra smooth surface flosses. It just works really well. I went from having number 3 and 4 pockets in my gums to mostly twos and an occasional 3 using this floss. Yes, maybe I floss more often, but I swear by this stuff.

Natural Silk Floss - Unflavored

I recently stumbled upon the Radius silk floss after learning my regular store bought floss was likely made from petroleum. So far I really like it and knowing I am not using a petroleum based product on my gums makes me happy.
