In my perpetual quest for the perfect pen eyeliner I finally got Maybelline's that has been on my wishlist for years. I tried to get Clio eyeliner to finally behave, but gave up and bought this one because it's one of the cheapest ones online. It's a classic felt tip eyeliner with an applicator that is said to be 0.4 mm wide at the tip. 

This is a liner that I feel L'Oreal, who owns Maybelline, felt super lazy and just copied the design and formula from L'Oreal Super Slim. I've compared the applicators and they also almost identical, meaning long with a sharp tip (in this post I only have the comparison with L'Oreal's Superstar eyeliner, but I'll have it with Super Slim in a future post). You can do a flick, but I find it hard to do very precise work, like trying to smooth the top of the line without making it wider as you can see on my picture bellow. It's a nice, basic liner that does its job, but it has exactly the same problems as L'Oreal's and that is that as it ages, the less product ends up on the tip, so flicks are more problematic to do. But such applicators retain a ton of product close to the base, so you can draw with it sideways and you'll have plenty of ink for a long time, however, you'll have to stick to just lining the lash line and forget about the flicks. So far my liner works ok,  though after two months it's already stating to lose colour in the tip.
The formula is nicely black and lasts well, though the flicks can wipe off during the day, ...
