I love this!
It is sold at Superdrug/ Boots and many other shops have Rimmel concessions
It's cheap, I can';t remember exactly how much it cost but it probably wasn't much more than £4 or £5 as the Rimmel products are all quite inexpensive.
The packages is nice and sleek, doesn't take up too much room in you make up bag!
Unfortunately this sat in my makeup bag for months before I worked out how to use it!
I had been (stupidly) trying to apply the liquid eyeliner to the inside of my eyelids! Don't try this at home because it doesnt really work and can irritate your eyes!
Now I just use it on the tops of my eyelids, and flick a little bit out at the corner of my eyes sometimes! depending on the mood :)
Word of advice...try to steady your hand by resting it on your cheek when applying this or else it can all go very wrong!
