I've been using this eyeliner for years, and I highly recommend it. It has great color, definition, and hold - it doesn't smear or run throughout the day like other ones. The color Celadon is hard to find, but it's worth the search. I have brown eyes, and I think the color is a nice compliment without being overdone.
This (Marine) is my third color of this eyeliner. It applies smoothly and easily. When sharpened, it's very easy to tightline with this eyeliner. The Marine color is very flattering and doesn't appear obviously blue when I'm wearing it. It just makes my eyes brighter. I don't have oily eyelids and can wear this all day and then overnight and it's still in tact the next day. I don't recommend that, but it's happened a few times.
This eyeliner is long lasting, easy to apply and easy to sharpen with it's built sharpener. It also goes a long way. I do use a eye primer and apply eye shadow to set it- but that's just how I do all eye makeup. Cassis is the best color. A nice plummy black that is dark but not too harsh. Get it.
I have worn this eyeliner for years & it's my fave. Can't live without it. The espresso is a perfect shade of dark brown & not too dark even if you're light skinned. Only wish it lasted longer...small amount for the price point.
