Give your lashes a curl. Carefully remove lashes from the tray. Using your tweezers or fingers, gently lift the band up from the outer edge. When you’re ready, put the lash in The Lash Tool or your fingers. Then apply a thin line of glue. Let it set for 15 to 20 seconds, so it gets tacky. Bring the lash straight on in (not up or down). Get as close to your lash line as possible. Adjust as needed.
