Why You’ll Love It
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.
How to Work It Into Your Routine
Shake lightly before use. Glide the brush tip along the lash line, starting from the inner corner and extending outward. Build thickness or create a wing as desired.

Honest reviews from skincare lovers around the globe.
It's thin and soft, so it's easy to draw, and the line finish is very beautiful, so I recommend it! It keeps a beautiful line even after a long time, and it's easy to match with various makeup styles. The intensity and finish are good♪♪
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 bought this to put glitter in. I usually use this eyeliner, so it fits comfortably in my hand.
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 :)
