I have repurchased this liner in the dark brown shade several times and it seems to be a great match for a lot of the dark brown and burgundy colours I love to wear.
It's a straightforward non-retractable pencil, but it seems to sharpen up nicely. I loathe pencils that disintegrate into splinters and break tips during the sharpening process!
It gives a precise line and seems to last well without bleeding. It doesn't ever seem to feel drying and the same pencil lasts a long time.
I haven't found a perfect pencil colour match for every single one of my favourite lipsticks in this range, but I'll happily buy it whenever I can find a match.
I really liked this lip liner! Can't remember what the name of the shade was but it was a dark red/purple colour. I'm only giving it a lower score because it doesn't having "conditioning" colour and it is not retractable. It was really soft and highly pigmented and a good colour to wear under MAC Dark Side for example. It was slightly drying though so definitely one to just use to line your lips - not fill it all in. If you're not too fused about having to sharpen it (I'm just lazy) then this a good lip liner to try out :)
Tips: Don't leave the lid off! Mine dried out.
