Lashes by M.A.C Cosmetics Lashes are handmade to exact specifications. Each pattern and design is perfectly shaped and arranged to give a striking effect, whether the look is natural or dramatic.Available in a variety of shapes and densities. If properly cared for, lashes can be reshaped or adorned if desired. Product Usage: Trim full lash to fit your eye shape/length. Apply a small amount of lash glue to the strip and allow 30 seconds for glue to become tacky. Position the strip at the base of your natural lashes and gently press onto the lash line. If properly cared for and cleaned, lashes can be re-worn and reshaped.
