What it is
A liquid eyeliner that brings out the impression of your eyes with its rich color and sharp lines. It uses a thin, stiff brush that makes it easy to draw a beautiful line all the way to the tip. It contains pearls for a glossy color. It is a water-resistant type that dries quickly and does not smudge for a long time.

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 runs out quickly so it's not cost-effective, but there's nothing better at preventing smudging, so I'll keep using it.
It's a metallic color, and I don't have any other similar colors, so I chose 07 from Suzykirei shopping. I bought 04 in-store. I adjusted the liquid and applied it to the edge of my lashes. It gave my eyes a bold look, and although I've only used affordable liquid eyeliners, I find myself using this one more often.
It doesn't come off at all, so I keep buying it. It's easy to write with.
It's so easy to apply! I wanted a pearlescent eyeliner, so I read the reviews and bought it. First of all, I thought that a brush pen type would be easier to apply, but I wonder, maybe the brush is different. It even glides smoothly onto the outer corner of my eye! This one feels great. 02 is brown, but it has a metallic feel, and it looks different depending on the angle, giving it a different nuance. If they come out with a black metallic one, I'd buy it straight away!
I've bought this many times. I'd be so sad if it were discontinued. It never smudges, even when I'm working overtime until 11pm. I've tried many other eyeliners, but I haven't found anything that beats this one yet.
