I bought this felt tip eyeliner in Italy during our holiday in May.
It then struck me as being a very good one since after I tested it on my hand, it was almost impossible to get it off. Waterproof? indeed!
So, bought it and now started to use it.
You can draw a very fine line with it, the dark is really dark, and the precision is excellent. Plus it really stays that way all day long. Even after taking a shower it just doesn't come off. So see to it that you have a good make up remover at home. ;-)
