3650 Liquid Eyeliner (Cassis Black)

(1) Waterproof and smudge-proof — holds against tears, sweat, sebum, and rubbing all day
(2) Master-crafted brush lets you draw both hair-thin lines and bolder strokes with control
(3) Removes easily with warm water — no harsh rubbing or dedicated remover needed

Most liquid liners make you choose between a brush that performs and a formula that lasts. The 3650 Liquid Eyeliner doesn't ask you to compromise. The artisan-crafted brush — blended from three different bristle types — gives you that rare combination of control and softness on the lid, so lines go down exactly where you want them on the first pass. The octagonal barrel sits steady in the hand and stops the pen from rolling off a counter. It dries fast, doesn't transfer to the crease, and holds through a full day without lifting at the corners. The 11-shade range covers everything from a strict black to softer options like Ash Black, Grey, Sheer Brown, and Khaki for a less defined, more diffused eye look — which makes this a useful Japanese waterproof eyeliner whether you're going for a graphic wing or a softer everyday line.

(1) Panax Ginseng Root Extract: energises and conditions the delicate skin along the lash line
(2) Panthenol (Vitamin B5): soothes and supports the skin and lashes with each application
(3) Loquat Leaf Extract: calming botanical that helps protect sensitive eye-area skin
(4) Pearl Extract (Hydrolyzed Conchiolin): nourishing ingredient traditionally used in Japanese beauty for skin softness

Starting from the inner corner, draw the 3650 Liquid Eyeliner along the upper lash line in short, connected strokes for the most control, or in a single gliding pass if you prefer. For a fine line, use the very tip of the brush with light pressure; for a thicker line or wing, press the brush down slightly and extend outward. Allow a few seconds to dry before blinking to avoid any transfer. Remove at the end of the day with warm water and a gentle cleanser — no separate eye makeup remover needed.

Q: How is the 3650 Liquid Eyeliner different from other Japanese waterproof eyeliners?
A: Beyond its waterproof formula, the 3650 Liquid Eyeliner is notable for its artisan-made brush — crafted from three blended bristle types — which gives a more controlled, precise application than most mass-produced liner tips. The octagonal barrel also makes it easier to hold steady, which helps with fine lines and flicks.
Q: Does the 3650 Liquid Eyeliner require a special eye makeup remover?
A: No — the 3650 Liquid Eyeliner is designed to come off with warm water, though a gentle face wash or micellar water can help if needed. No oil-based remover is required, which makes it particularly convenient for daily use.
Q: Which shade of 3650 Liquid Eyeliner should I choose for a soft, everyday look?
A: Sheer Brown, Beige Brown, and Grey are the most wearable for a subtle everyday line. Ash Black and Brown Black sit between soft and defined — good if you want more presence than a brown but less intensity than a full black. Khaki is a popular choice for adding a slightly editorial edge to everyday makeup.
Q: Does the 3650 Liquid Eyeliner transfer to the upper eyelid crease?
A: The quick-dry formula is specifically designed to prevent transfer to the eyelid after application, which makes it more comfortable for monolid and hooded eye shapes where the lid frequently contacts the liner.
Q: Is the 3650 Liquid Eyeliner the same brand as 3650 San Roku Go Zero?
A: Yes — 3650 is the brand name, read as "San Roku Go Zero" in Japanese. The name is a reference to the 365 days of the year, reflecting the brand's philosophy of everyday wear.
