Designed for both lash pros and beginners, DUO’s Line It Lash It in Black is the revolutionary 2-in-1 eyeliner and lash adhesive that lets you glide smoothly on your lash line.

With a intense black shade, this combo eyeliner and adhesive lets you finish off with well-defined and prominent eye makeup that can hold up all day (or all night!).

Comes with a fine tip applicator brush to help you draw a thin and intensely pigmented black line with precision. Even if it’s your first time!

Now you can get lash extensions as easy as applying eyeliner to your lash line.
