It’ll be hard to forget to floss when this attractive glass bottle is on the bathroom vanity. It’s a striking little bottle. And inside is a refillable spool of mint-flavored bamboo charcoal floss that leaves teeth and gums feeling clean in a way conventional plastic floss just can’t. Something else plastic floss can’t do? Recycle. Ditto for the plastic packing in which it arrives. Style, substance, sustainability. Hard to forget a floss that can do all that.
