N.A.F’s Extreme Slender Waterproof Eyeliner Pen (Black) delivers a razor-fine tip for precise, hairline strokes and defined wings. The pen’s quick-drying, waterproof finish suits long-wear looks and daily use for steady-handed users or anyone seeking smudge-resistant definition. Lightweight in application, it’s aimed at those who prefer a controlled, precise liner rather than a heavy, creamy formula.
