How to use
Cut a length of floss about 40cm long and wrap it around the index fingers of both hands, keeping the space between your fingers 6cm and pulling it taut. Pass the floss between your teeth and slowly move it up and down. When moving on to the next tooth, shift the floss about 3cm so that the new floss touches the tooth.

Do you offer express shipping?
Yes. As of 22 July 2026, we offer International Express Mail through Japan Post. The cost is based on order weight and is calculated automatically at checkout.
Will I pay customs or import fees?
US orders: No. As of July 1, 2026, all US orders ship DDP (duties delivered prepaid), meaning we prepay all import duties on our end. Nothing is due at your door.
Orders outside the US: Possibly. Duties and import taxes are set by your local customs authority and are not collected at checkout, so any charges on delivery are your responsibility.
We're working on rolling out prepaid duties for more countries soon.
