blinc's original liquid eyeliner was invented to form a water-resistant "layer of color" that contours your eyes. Since blinc eyeliner is not a cosmetic paint, it cannot smudge, run or flake - even if you cry or rub your eyes. In an easy to use, convenient, marker-tipped pen, blinc's liquid eyeliner can be applied with precision. It glides on smoothly and the ultra fine tip provides for extreme accuracy, allowing you to create virtually any look you desire, from a thin classic line, to dramatic, winged looks. blinc eyeliner is ideal for those with sensitive eyes, contact lens wearers, performers and active people in search of eyeliner whose look, hold and ease of removal is without compromise. blinc eyeliner does not penetrate your skin, leave any tint or residue behind or require harsh makeup removers.
