I have to admit that the combination of the words 'semi-permanent' and 'liquid eyeliner' sent a bit of a shiver down my spine before I tried this product. I've not got the steadiest hand in the world and have never quite perfected the fine art of eyeliner application. How would I cope with a product I couldn't instantly remove? The first thing I noticed about the pen itself was the firmness of its fibre tip: this made application far easier than using a bruch or pencil, so it's actually great for those of us who find it hard to draw a straight line. When I did slip up, a quick dab with some makeup remover got rid of the marks as quickly as with any liner, so I was free to experiment. I was particularly impressed by its ability to draw a tiny, fine line underneath the eyelid - the trickiest area of all!
