Want an eyeliner that goes on smoothly, stays all day, and works for everything from a clean everyday line to a full smoky eye? FLEX does it all.

This gel-based pencil is ultra-creamy, so it glides on without pulling or skipping — even on the waterline. High-impact pigment delivers rich, saturated color in a single stroke. Once it sets, it locks in waterproof, smudge-resistant, and long-wearing for all-day definition.

The retractable, twist-up design means no sharpener ever needed — just twist and go. The formula stays workable for a few seconds before locking down so you can smudge, blend, or wing it out while you still have control.

Artist tip: FLEX doubles as a cream eyeshadow. Smudge it out with your fingertip or a brush before it sets for a soft, smoky finish — no powder shadow needed. Available in Black, Deep Brown, and Medium Brown. 100% vegan and cruelty-free.

Available shades: Black — deep, rich, classic. Deep Brown — warm dark brown for softer definition. Medium Brown — versatile medium tone ideal for natural everyday looks.
