When I tried this I fell in love. It's a great eyeliner. Very dark, very pigmented, lasts all day long, and has a very precise tip that makes it easy to use. However, once I had it a little over a month it dried out. I ended up having to throw it out because it just wouldn't show up at all anymore. With Marc Jacobs being as pricey as it is, you would think their products would last at least a few months...
