Soft & Smooth cleaning

The silk is spun in candelilla plant wax (derived from candelilla shrubs in the Southwestern US desert), ensuring a smooth glide between teeth for total tooth and gum protection and maximum cleaning.

All natural, no nasty

Our floss is 100% biodegradable and free of glutens, preservatives, artificial sweeteners, GMOs, unnatural coloring, phthalates, parabens, or any other harmful additives.

Floss for the people

Our pure silk thread is spun on small machines at the CORSEDA Fair Trade Co-op in Colombia, which supports more than 80 families.

Appreciation post

I’ve never sought out the website of my floss company before - but tonight... I truly wanted to. *I love this floss* It’s silky, strong, and actually pretty fun to use. Cardboard box, biodegradable, and compostable. I appreciate! My first time trying your brand. I’ve been hooked.

Reducing plastic

Can you please offer an option of a cardboard floss container for those of us reducing our use of single use plastic?

Thank you for your feedback. Check back Spring 2019 for new floss with plastic free packaging!

Love your Floss

Would you consider selling refill floss to pop into your plastic cases?
It would save on all the little cases in the trash!

As much as we try to be environmentally friendly as possible, we need to follow FDA laws. The FDA requires it to be packaged in a plastic container when sold in traditional retailers such as grocery/drug. Since we sell in both natural stores and traditional stores we must abide by this law. We are always looking for new, innovative, green ideas for packaging and are actively looking for alternatives including separate packaging for natural retailers.

One alternative that we offer is our Floss Sachets. It’s the exact same floss as our spooled floss except it’s packaged in single-use travel size quantities. Each sachet has enough floss for one use and you can purchase them in packs of 20. These are packaged in biodegradable paper. The reason we can sell this floss in a non-plastic container is because the paper sachets are air-tight and that’s an acceptable alternative for the FDA (we are also looking at this idea for our spools).

We appreciate your feedback and suggestions!
