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.

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's easy to draw thin lines, so even black lines look modern. It didn't smudge even after a day. It's easy to draw, so I recommend it for beginners.
I won the X campaign and received this product! Thank you very much :) The tip is super fine and flexible, so I think I'll be able to use it until the very end without it getting worn out. It's so easy to apply! I don't usually use liquid eyeliner, but I was surprised at how easy it was to use for filling in the gaps between my lashes! I also like that it comes with a refill, which seems environmentally friendly. I'll consider repurchasing it once I've used it up :)
The brush is very thin and delicate, so you can draw even the smallest details!. The color is very good, so even thin lines look clear. It's easy to draw because it doesn't shake at all, and it doesn't smudge, so there's no need to bother touching up!.
I bought this to put glitter in. I usually use this eyeliner, so it fits comfortably in my hand.
It's so thin! Because it's so thin, you can't complete your eyeliner application in one go, but it's easy to hold and has a diamond cut design so the pen doesn't slip off, making it easy to apply. I tried using it as an eyeliner, and it didn't smudge or come off even when rubbed. I thought it was resistant to tears and sweat, and since the packaging says to use makeup remover, I thought it might be difficult to remove with hot water. However, I used cleansing and it came off easily. The color is jet black as the name suggests, and I'd like to use it when I want to apply strong makeup. However, it also seems to go well with pink-toned makeup.
