Lashes should be applied when makeup is complete and your natural lashes have been given one or two coats of mascara. Use lash comb if necessary. Carefully remove the lashes from the tray and check length against your eye. If too wide, trim one or two at a time from the outside edge until the fit is perfect. Look down into a mirror and hold lash as closely as possible to the natural lash line. Press gently, holding at the ends for a few seconds. Additional adhesive included.
