Apply your makeup and mascara on your lashes. Carefully remove the strip lashes from the tray using the tweezers. Measure the length of the lash against your eyes and trim if required. Apply a thin layer of lash adhesive along the trip and then wait for 30 seconds. Apply the eyelash towards the middle of the lash line, as close to the root as possible and gently press it in place. (Optional): Give your lashes a curl and another coat of mascara.
