I have tested by me through so quite a few eye shadow Bases of drugstore to high end. The price performance ratio was right here simply. The base eyeshadow intensifies, extends the shelf life and nothing warps in the crease. According to the manufacturer it is to make the eyeshadow even waterproof. I have not tested. But it really is a top quality product and worth every penny. I have my potty now probably already half a year and use it every day. That thing is still almost to the brim.
