Lash glue and eyeliner at the same time! Easy to use, no mess, and easy touch ups! Perfect for everyday use. This 2 in 1 adhesive eyeliner is definitely a game changer! TIPS: Store adhesive liner vertically, cap side down, to prevent from drying out. It is formulated to last all day, but oily skin might require reapplication during the day. Line your lid generously, to create a sufficient base for the width and length of lash band you are applying.
