This natural floss is made from a blend of Charcoal Fibres and compostable Corn-base PLA, coated with Vegetable Wax and organic Peppermint Oil. Studies have shown Peppermint oil to be extremely effective at killing anaerobic bacteria, left untreated this bacteria can cause gum disease. Please Note: Our improved floss is now 20m longer meaning our previous containers no longer fit our new floss. This change increases the product's sustainability and also reduces the effects of shipping. Note: our floss is now 20 metres longer, meaning our previous smaller dispenser no longer fits.
