COSNORI Super Proof Fitting Brush Eyeliner 0.6g (3 Colors)

COSNORI Super Proof Fitting Brush Eyeliner: Long-Wear Brush-Tip Liquid Liner in 3 Shades

COSNORI's Super Proof Fitting Brush Eyeliner is a long-wearing liquid liner with a fine brush tip for precise application, formulated to resist smudging, sweat, and oil transfer through a full day of wear. Available in 3 shades, the liner uses a quick-dry ink formula that sets within seconds of application and stays put without reapplying. At 0.6g and $20.80, this sits in the mid-tier Korean eyeliner category.

Korean eyeliner preferences lean toward fine-tip precision and long wear over extreme color payoff. COSNORI is a Korean color-cosmetics brand known for accessible-priced products with formulations that compete with premium labels. The Super Proof line is their waterproof/smudge-proof category, designed for humid Korean summers and long commute days where touch-ups aren't practical.

What It Does

A fine brush tip enables precise line control from hairline-thin to full wing thickness. The ink formula dries within 10 to 20 seconds of application, then resists water, sweat, and oil transfer. Not fully "waterproof" in the swim sense, but sweat-proof and smudge-proof for typical daily wear. Lasts 10 to 12 hours on oily lid skin without setting powder.

Who It's For

• Fine-line preference users: Brush tip delivers control from thin to thick lines.
• Long-wear demand: Commuting, work, sport, humid climates.
• Wing-tip or cat-eye creators: Precise tip handles sharp outer-corner wings.
• Oily lid users: Smudge-resistance matters more on oily eyelid skin.
• Mid-tier makeup budget: Performance tier without luxury pricing.

How to Use

Shake before use to distribute ink into the brush. Start from the inner corner of the lash line and work outward in short strokes. For a winged look, extend the outer corner with a single flick upward. Allow 10 to 20 seconds to dry before opening eyes fully. Remove with an oil-based cleanser or dedicated eye makeup remover at end of day.

FAQ

How waterproof is it?

Sweat and smudge-proof, but not swim-proof. For pool or beach wear, use a dedicated waterproof (not water-resistant) formulation. For typical humidity and daily sweat, this is sufficient.

Will it remove easily?

With oil cleansing, yes. With water alone, no. Use a cleansing oil or dedicated eye remover on a cotton pad; hold for 10 seconds over closed lid, then gently swipe. Don't scrub the eye area.

How does this compare to Etude House Drawing Show?

Similar price tier, different tip. Etude Drawing Show uses a felt tip (firmer, good for bold lines). COSNORI Super Proof uses a brush tip (softer, better for thin and tapered lines). For ultra-precise thin lines, COSNORI. For bold thick lines, Etude.

Does the ink dry out quickly?

Typical shelf life after opening: 6 to 12 months. Store upright and cap tightly between uses. If the ink begins to skip or apply unevenly before the expected lifespan, it's likely starting to dry out and should be replaced.

Is it safe for contact lens wearers?

Generally yes, applied to the outer lash line (not the waterline). Avoid applying between the eyelid and the eye itself. If you have sensitive eyes or allergies, test a small amount first.
