We loved everything about Fresh Lab’s Corn Floss: it is vegan, compostable, refillable. It doesn’t shred at all and it gets in between both our tight contact teeth and our slightly wider gaps. Sadly, it is the most expensive floss we have ever used, so on the basis alone, the floss is NOT a buy from us.
If you don’t mind spending an extra $20/year per person for the diligent flosser who wants a vegan, compostable floss, then we can’t recommend this enough.
