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.

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.
I love NANA, so I bought this because of the NANA collaboration. It's a little short on volume, but it stretches like crazy!
I'm a self-proclaimed mascara geek. At 50, I wanted to add volume in a natural way. This time, I decided to try two types of Kate mascara. Both are described as lengthening and volume. This one has a slightly gentler brush curve. I think ease of use is a matter of personal preference. The texture is also smooth, so if you want to add volume, you may need to apply multiple coats. I bought the brown one, and it gives a soft finish to the eyes.

I've always used KATE mascara, along with the primer. My lashes are so thin and weak that even popular curl-keeping mascaras make them droop easily, so I need a mascara that sets like this to last me a day... If I apply both this and the primer twice, my lashes stay almost the same as when I first applied them, even if I'm wearing a mask or caught in a strong wind. The finish is far from achieving the sleek, delicate lashes, and the fibers tend to fall out easily, but this mascara is an essential for me.
I bought this together with Kate's eyebrow product. It matches my eyebrows and eyelashes and is easy to use.
