Eyeliner pencils give you a perfect eye definition, enabling you to change and/or enhance the shape of your eyes. As such, they have been loved since ancient times (think Cleopatra) throughout the modern times (guyliner is such a hit!).
I was looking for a dark grey shade and I found one within Catrice cosmetics range. (070 cool grey). What I like about this eyeliner is that it is soft enough to transfer the colour yet has a reasonable staying power and also the sponge tip for optional smudging. The price is 2,49 EUR at Kruidvat.
