ILASHMAX Riche Mattte Flat Lashes are super soft, flexible with no "sheen", true black ( no blue hue) color for dramatic look. Our matte flat Lashes are concave on the base, flattened for wider look, creating more surface for a better bond between natural lash and eyelash extensions, resulting lash much longer than normal. Thickness 0.15 flat lashes LOOK like 0.20 and FEEL like 0.10. The concave surface wraps around the natural lash prevents from turning or twisting from the natural lash. The flat Lashes are lightweight and have luxurious feel.
