The brush head is super tiny and really thin meaning that the liner can get as close to the eyelashes as possible.
The handle is just as long as other Real Technique brushes so you don't have to worry about controlling the brush head (I find that longer brushes are easier to control... just me?)
The NYX Gel liner caught my eye straight away as I'm currently a bit fan of gel liners. Apparently you can use this liner to smudge onto the eyelid too, but I haven't tried that yet.
I bought the dark brown shade.
The Gel liner comes in a tiny little glass pot with a plastic lid. At first I thought it looked really dry but upon application I found it to be quite manageable and creamy.
