FAQ
Why is this floss black?
The thread is made from bamboo fiber coated with coconut charcoal, so it's naturally black rather than dyed. The dark color is functional: pale plaque and food debris show up clearly against it as you floss, so you can see what you've actually removed.
Does the charcoal actually whiten between my teeth?
No — this floss makes plaque visible, it doesn't bleach. The coconut charcoal serves as a high-contrast backdrop that reveals the soft plaque you lift out; removing that plaque regularly is what keeps interdental surfaces cleaner and less prone to staining.
What does "expanding" mean and is it comfortable for tight contacts?
The bamboo-and-charcoal thread slips in thin, then expands to fill the gap once it's between the teeth. That lets it sweep a wider surface of the tooth and gumline in one pass, while still starting narrow enough to pass tight contacts.
Who is this floss best for?
It's aimed at people who want visual feedback on their cleaning — anyone building a flossing habit, and stain-prone users who want to confirm they're clearing plaque before it mineralizes. If you already floss confidently and don't care to see the debris, a standard thread works just as well.
