Primo Lash - $48. The longer, darker, fuller lashes you dream of are just a sweep away! PRIMO LASH serum contains breakthrough, patented Peptide Technology to dramatically transform the look of your lashes. Paraben, Gluten, and Sulfate free. This company even has an "auto-replenish service", which is pretty cool.
Also, I love the fact that they put Beauty DNA stickers on their products. This actually helps me remember later on where I got the item from.
