Frequently Asked Questions

Is this authentic?

Yes. Every item is bought from an official seller in Japan, or direct from the brand for pre-orders,

never from resellers or grey market stock. Counterfeits and grey market listings are a real problem in

Asian beauty online, and buying only through official channels is how we rule it out.

What are your shipping rates?

On orders under US$75, shipping is a flat US$20 to the United States and US$10 to all other countries.

Orders of US$75 or more ship free, applied automatically at checkout. Your exact shipping cost is shown before you pay.

How long does delivery take?

These estimates are for International Airmail (Tracked) and include 3 to 5 business days of processing in Japan.

  • United States: 12 to 15 business days
  • Canada, United Kingdom, France, Germany: 9 to 12 business days

Actual delivery can be affected by customs clearance, seasonal congestion, or carrier delays in the destination country, all of which are outside our control.

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.
