Unless you're using an electronic tool, odds are your toothbrush is made of plastic. Which means it's eventually going in a dump. The Goodwell Toothbrush aims to put an end to that. It has two pieces: a compostable head with Binchotan fibers that fight plaque, bad breath, bacteria, and viruses, and a reusable anodized aluminum handle that doubles as a storage container. Buy it alone, as a kit with a biodegradable flosser and tongue scraper that hook up to the same handle, or get a subscription that drops new attachments at your door each month.
