Waterproof Black Eyeliner Pen – MB Cosmetics BZ

Define. Glide. Lock.

Master sharp, dramatic wings and smudge-proof lash lines with zero effort. The MB Cosmetics BZ Waterproof Black Eyeliner Pen combines a high-pigment liquid black formula with a specially engineered soft sponge tip, giving you complete command over every stroke—from delicate daily tightlines to bold, graphic liner looks.

Designed for long-lasting performance, this sleek felt pen deposits rich, continuous jet-black pigment that sets quickly and resists water, sweat, and humidity. The flexible soft sponge tip glides gently over sensitive eyelids without tugging, skipping, or fraying, ensuring a seamless application every single time.

Why It Stands Out:

• Waterproof & Smudge-Proof: Formulated to resist moisture, sweat, and oil for long-wearing intensity that stays locked in place all day.

• Soft Sponge Tip Applicator: The gentle, flexible sponge nib allows for smooth liquid flow, effortless ink distribution, and comfortable application across delicate lids.

• Precision Line Control: Easily transition from subtle, ultra-thin lash enhancement to dramatic winged tails simply by adjusting hand pressure.

• Intense Jet-Black Payoff: Delivers rich, opaque black pigment in a single pass without fading or flaking throughout the day.

• Net Weight: 0.6g

How to Use:

1. Shake Well: Gently shake the pen before use with the cap facing down to activate liquid flow.

2. Trace the Lash Line: Place the soft sponge tip close to the root of your upper lashes and glide from the inner corner outward in smooth, continuous strokes.

3. Flick the Wing: Angle the pen tip toward the end of your eyebrow, press gently to set your guide line, and connect back to the lash line to fill in your winged tail.
