This is my favorite eyeliner!!! The brush is very convenient, it feels much easier to draw on a wing with it. There seems to be plenty of product in the jar, and I think it's water-resistant, I need makeup remover (or a cleansing oil) to remove it. The only I'm not loving is the packaging, it looks good, but it's inconvenient because it takes up a lot of space in your makeup bag because of the wide base (but there are alternatives I guess, like a separate pot and brush). I'm going to keep repurchasing this eyeliner, I think! :)
