Okay so I have a love/hate relationship with this stuff. The fibers really do lengthen lashes and make your lashes look SOO much fuller. But the problem is a lot of times the fibers fall into your eyes and actually are really irritating. I've learned to put the fibers on Immmmeaditly after the mascara. I'm talking like as soon as possible. That helps the fibers stick better and not fall off as much. Over all it's great for the days you need an extra confidence boost, but maybe not everyday use.
