After some days of hunting, I finally found it in stock at our local Sainsbury's.
I must be honest I thought that I would discard the brush that comes with it and choose to use my own MAC angled liner brush.
Well, I couldn't have been more wrong! The brush is only small so great if you want to pop in your handbag makeup bag and not bad quality at all.
In comparison to MAC's fluidline, it does feel more lightweight. It glides easily over the eyelid and is a strong, solid back.
The only issue that I have, is I find that throughout the day it does smudge up under my crease bone, which MAC Fluidline doesn't tend to do.
In all, for the price this is a good product and I would buy again to use as part of my everyday makeup. I have high hopes that they may now extend to some further colours as currently this is only available in black.
