Georganics
Georganics designs for less waste rather than for zero plastic. Its beechwood toothbrush has a snap-off replaceable head and a mail-back head-recycling scheme - a genuine waste-reduction win - but the bristles are still nylon. That makes it a waste story, not a plastic-free one: the part touching your teeth is plastic, however cleverly the rest is designed to be reused.
How clear are their specs?
Names the FSC beechwood handle and the nylon bristles plainly, and documents the replaceable-head and mail-back recycling design, so the tradeoff is easy to see.
