If you have mature skin and hooded or downturned eyes, the manoeuvrability of the tip on this liner pen is an absolute gamechanger. This is not the most pigmented of all the liquid eyeliners, which means if you apply it very shortly before curling your lashes then it *can* fade a little after it makes contact with the clamp. When this happens, I either apply a light second coat (no caking) or line on top of it with the Natasha Denona pen, which doesn’t have *quite* the same hyperprecision but does have superb pigment. Surratt Autographique is one of the precious few liquid liners I will definitely re-buy, and already have. 

Best eyeliner I ever had in my life. Found it recommended by makeup artist AndreeaAli and decided to give it a try. I will never buy anything else. Can build on what Swalk said, super soft brush, and when you paint the line, the colour just keeps on coming, it's just amazing. 10/10

I absolutely loved the intensity of the liner & the tip was great for drawing a very precise line. I liked the fact that it's refillable as well. Unfortunately, the eyeliner always smudges on me after wearing it for a couple of hours (even with wearing eyeprimer). Probably depends on the person, however this liner wasn't for me.

This certainly the best eyeliner I have ever used - the brush is sublimely soft and oh so precise, colour is good also - the pen itself is easy to hold and refills are ink cartridge; doesn't get any better.

Although pricey this is the best eyeliner I have ever owned. I am willing to shell out as I use it every day and the ink cartridges last for many months so it's definitely worth it. The brush is fine and soft and doesn't spray like many others so is good for precision, stays on all day too!
