I'm pleasantly surprised with how much I like this brow pen. My eyebrows don't exist anymore so I'm constantly looking for a pen which is the right colour and which can replicate something close to fine hair rather than a solid block of colour. As a mature woman, I want my eyebrows to look as natural as possible. This is the best brow pen that I've used so far, that can mimic natural hairs. It lasts all day, even in the very hot weather that we've been having.
