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
- Australia, New Zealand, Denmark, Finland, India, Indonesia, Italy, Netherlands, Spain, Sweden, Switzerland: 10 to 13 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.
The next morning feels great!
When I took it out of the bag, it was very sticky and slimy. It was a little difficult to apply around my eyes and mouth, but it adhered to my face very well and was extremely moisturizing. The scent wasn't particularly bothersome. After peeling it off, I smeared the sticky residue on my arms, lol, and was surprised at how moisturizing it was the next day. I used it on an ordinary day, but I plan to use the next sheet the day before an important event.
The mask was covered in a thick liquid that adhered perfectly to the skin without floating. I had been in a sauna that day, so my skin was a little red and dehydrated, but after 20 minutes, when I removed the mask, the redness disappeared. While thick masks often leave a lot of liquid on the surface of the skin after removal, this mask penetrated deeply into the skin, leaving very little liquid remaining. It also moisturized my skin both internally and externally in a balanced way. It didn't make my skin super clear or revitalized, but it did help balance my skin!
Since this lotion and cream were a perfect match for my skin, I was also curious about the newly released mask, so I bought one. It's a two-piece mask, with thick, bouncy sheets for the top and bottom of the face. It's a little tricky to align it to the right parts of your face, but the sheets adhere well and don't peel off. Plus, the color changes from white to transparent as it penetrates into the skin, which is great. It's typically worn for two to three hours (perfect for a mask while using your smartphone, etc.), and it can also be used as a night mask. I tried using it before bed, but I found it uncomfortable and suffocating to sleep with something on my face, so I ended up taking it off halfway through. Even so, more than three hours had passed, and my skin felt moisturized and plump when I woke up in the morning. While the noticeable effects are noticeable after just one use, the price per mask is a bit steep, so I'd like to repurchase it if I can find a good deal on a sale.
