The highly pigmented liquid liner formula delivers a bold eye look that is smudge-proof, flake-proof and smear-proof and with no mess or excess. The neon pigments react to glow under UV black lights to fluoresce with bright colour. The Neon glow is very striking and will get you noticed in the club or festival. Use the liner for intense definition, the thin brush supplies smooth, even lines for lasting intensity with the brightest colour possible.
