The thinnest, softest, waterproof gel liner. Encapsulated in a 1.5mm mechanical pencil, this liner offers precision accuracy and ease of application. No pot, no brush, no clean-up required. Just two clicks and one stroke creates dramatic definition that resists transfer for extended wear. Available in a package of 3.

The precision 1.5mm tip ensures effortless control, and allows for lining in between lashes. The unique formula, poured into a slim mechanical component, has the malleability, intensity and staying power of a traditional gel. No pot, no brush, no clean-up required. The waterproof, transfer-proof and long-lasting formula delivers extended wear. The supple, moisturizing formula glides on smoothly and dries quickly. Two clicks is all you need to line the eye. Each advanced mechanical pencil lasts for approximately 17 to 20 uses. Only dispense product as needed – mechanical pencil does not retract. Free of phthalates, sulfates, talc and gluten. No animal testing. Ophthalmologist tested.
