What it is
KATE Super Sharp Liner EX4.0 is one of those liners that makes detail work feel effortless. The ultra‑thin brush tip glides smoothly, allowing you to draw everything from delicate lash‑line definition to bold wings with total control. The formula is resistant to sweat, sebum, and humidity, yet removes easily with warm water. It’s the kind of liner you rely on when you need precision, staying power, and a clean, modern finish.

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's a nice brown color and easy to use, but sometimes the areas that are touched by the eyelash curler peel off.
It's good because it draws well without any unevenness.

It's easy to apply, but it doesn't last long. It seems to be particularly vulnerable to water. It comes off easily when your eyes get watery.
It's very easy to draw with, and the ink seems to last a long time.
