Hi this is my review of the ELF waterproof eyeliner pen, which can be purchased from http://www.eyeslipsface.co.uk/.
This was my first eye liner pen, I had mostly used pencil, as I wasn't very good at liquid. I like this pen, as it is very forgiving, so if i go wrong you can go over it with another line if you don't make your lines too thick.
Also I like the price at £1.50 you can't go too far wrong, but I am now starting to feel it dry up a little, but definitely still usable but the line may not be as smooth.
Overall I really liked this product and I have gone onto try other eye liner pens :)
