I was doing my morning routine and noticed the nylon thread I was putting in my mouth was plastic soooo I worked with a company to bring you this floss, it's bamboo with charcoal powder, the powder doesn't come off in your teeth but instead shows you what you plucked out. Also for me if it's out of sight its out of mind, so having it in this glass vial gets me to use it more. Made with ❤️.
