Do you make a biodegradable and vegan floss option?

We currently don't have a floss that is both vegan and biodegradable, but believe us, we've been on the hunt for this option for a long time. The issue that we've encountered is that, while you can find fiber that is both vegan and biodegradable, the key is to make sure it's also strong enough to be made into floss and so far we haven't found a thread that doesn't break easily and is up to our standards.
In the meantime, we have 2 options - a vegan non-biodegradable option, and a non-vegan biodegradable option. This is our best offer until we find that perfect fiber that's the best of both words BUT can also be made into floss.
