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.
It lasts longer than regular Kate eyeliner. I hope they keep selling it.
I bought BK-4 Ash Black because I thought the color I used was just right. I haven't used it in the middle of summer, but it doesn't come off. My eyelids overlap at the base of my lashes, and even then, it stayed on all day. The color isn't pitch black, but it's just the right amount of thin, so it doesn't look too loose, but it's nice and tight, and I thought it was a very easy-to-use color. The brush is also brush-type, so you can control the strokes from thin to thick, and you can even draw the edges of the very thin tip, which I'm very happy with. It's a shame that production will be discontinued on September 30th...

It doesn't come off easily and the color is exquisite! It's not too dark and blends in well. I use it as a dark eyeshadow that definitely tightens the eyelashes, so I draw a line and then fill in the areas I want to make darker. It's not too dark, so it creates a natural gradation. Affordable cosmetics sell quickly, so I stocked up on two this time. If I had to say, it might run out quickly, but at this price, it's totally fine.
It's thin and doesn't come off easily! It's amazing! I've been using another brand for many years, but I'm switching to this one. I mainly use black colors, but I'd be happy if they came out with browns and other colors someday.
