There are various materials that can be used to make eco-friendly floss. Including silk and PLA plastics. The former wasn’t an option for us as we wanted our floss to be vegan. Instead, we are using a bio plastic made from corn starch that can be composted. It is coated in natural candelilla wax and uses natural mint flavouring. Our containers are made from glass and stainless steel and are intended to be reused. Our refillable dental floss is a great way to take a small step into the world of plastic free - making this change makes a huge difference.
