How to use

Use approximately 1-2 times a week. Use after toning your skin with lotion. Can be used either morning or night. 1: Hold the handle with your right hand and slowly unfold the mask. Be careful not to drip. 2: With the handle on the right hand, align the mask with your eyes and mouth and press it firmly against your skin. Then, while lightly pressing the notch under your chin, hold the cheek area and pull each side up towards your temples, overlapping the mask to ensure it adheres firmly. Leave the mask on for 10 minutes, then remove it and massage any remaining liquid into your skin with your palms.

Frequently Asked Questions

Is this authentic?

Yes. We only buy from official retailers and directly from the brands here in Japan. Never resellers, never grey market stock.

We are beauty lovers too, so we know the worry, especially with something you are putting on your face. Authenticity is 100% guaranteed by us.

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
  • Australia, New Zealand, Denmark, Finland, India, Indonesia, Italy, Netherlands, Spain, Sweden, Switzerland: 10 to 13 business days
  • China, Hong Kong, Malaysia, Singapore, South Korea, Taiwan, Thailand, Vietnam: 8 to 10 business days

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.
