This is hands down the best eyeliner currently on the market in Japan, and it stays put for hours, even on mucous membranes! The color doesn't fade or smudge, even when applied over glitter, pearl, or cream eyeshadow, making it difficult to apply or prone to smudging! Amazing!! The moderately thin brush makes it easy to apply!! No more redrawing and touching up over and over, which can make it look messy and frustrating when you're short on time in the morning! No need to touch up your makeup, so it's great value for money! This is the perfect eyeliner I recommend to everyone in the world! Amazing!! P.S. I bought some to stock up on.
