The only brow pencil I will ever use . I bought one and have been buying more since (afraid it may be discontinued or something). My brows used to be dark but are more and more sparse and now turning grey with age. This one is easy to use, doesn't smear, is water proof if you don't use soap or rub off, lasts almost 2 days and has the right shade of dark grey. In the future, when all my hair goes grey, I hope they already sell a lighter shade of grey. I have been needing and trying all sorts of things in the past ten or more years and this is the best !
