Ardell LashTite Dark Adhesive 

ARDELL's permanent eyelash adhesive for eyelash clusters in black! Thanks to its dark color, the adhesive blends perfectly with eyeliner! The adhesive lasts up to two weeks.

Apply an appropriate amount of eyelash glue to the eyelash clusters. To do this, place a small dab of glue on the back of your hand and carefully run the knot or tip of the eyelash cluster through it. Immediately place the eyelash clusters between your natural lashes. Start applying at the outer end of the lash line.
