These 2 bamboo-based dental floss refills comes in cornstarch pouch, and the floss is strong enough to provide a highly effective clean. It is vegan and cruelty free, coated with candelilla wax, and infused with activated charcoal and peppermint essential oil. This combination of ingredients allows the floss to remove plaque, help keep the gaps in between your teeth white, and is gentle on your gums.

We use paper and cardboard packaging and dunnage to ensure it is shipped safely. Not using plastic packaging and minimal usage of other biodegradable / recyclable packaging is a key part of our mission as a brand of sustainable personal care and home products.
