Perfect my partner and I love it. No more plastic packaging, and far better alternative to regular commercial floss that has nasty paraffin in it. Easy to use, dispenses really well, gets in between teeth without breaking and flaking. So you don’t need larger length compared to other floss. Affordable and long lasting. We brought x 2 spares and x 2 canisters. Thank you for having this product to purchase. Very grateful.
