Flower Knows Liquid Eyeliner Ink Black — 0.01 mm Ultra-Fine Brush Tip, Waterproof & Smudge-Resistant

Flower Knows Butterfly Cloud Collar Liquid Eyeliner is a waterproof, ink-black liquid liner with a 0.01 mm ultra-fine brush tip for precise, long-lasting winged or everyday looks. This liquid eyeliner pairs an exceptionally thin, flexible brush with a silky, smudge-resistant formula to deliver crisp, even lines that resist transfer and water. The matte black pigment lays down rich color in a single stroke while the barrel design — inspired by the traditional Chinese Yunjian (Cloud Collar) — adds an elegant, collectible touch to your makeup kit. Vegan and cruelty-free, it’s made for people who want high-definition eye definition with ethical ingredients.

How precise is the 0.01 mm ultra-fine brush tip?

The ultra-fine 0.01 mm brush tip is engineered for detailed work along the lash line and for creating clean wings. Its flexible fibers respond to pressure, letting you modulate line thickness without switching tools.

• Extra-fine control for hair-thin lines or graphic liner
• Flexible tip adapts to eye shape and hand movement
• Even ink flow for consistent lines without skipping

Will this eyeliner stay put through the day?

The formula is both waterproof and smudge-resistant, designed to maintain crisp definition from morning routines through evening plans. It resists transfer on lids and under eyes while holding its matte, ink-black finish.

• Waterproof composition prevents running in damp conditions
• Smudge- and transfer-resistant finish reduces midday touch-ups
• Buildable pigment keeps lines bold without caking

How does the liner perform for different looks — natural to dramatic?

Because pressure on the brush controls line width, the liner is versatile enough for thin, barely-there definition or bold, dramatic cat-eyes. The smooth glide and rich black pigment make it simple to create uniform strokes and layered intensity.

• Light pressure for thin, everyday definition
• Heavier pressure for thicker lines or sharp wings
• Quick-dry formula allows safe layering and eyeshadow application

What makes the packaging and formulation noteworthy?

The slim barrel features cloud-collar-inspired blue floral and bird motifs influenced by classical Chinese art, making it attractive on a vanity and gift-ready. The product is vegan and cruelty-free, reflecting Flower Knows’ commitment to ethical beauty.

• Decorative Yunjian-inspired design for a refined presentation
• Travel-friendly size with secure cap to prevent drying
• Vegan and cruelty-free formulation for ethical consumers

It’s ideal for anyone who values a superfine brush for detailed work, long-wear reliability that reduces touch-ups, and an elegant design that blends traditional aesthetics with daily utility. Use it for subtle lash definition, sharp cat-eyes, or layered glam looks — the brush and formula adapt to your technique and pace.
