I have fairish eyebrows (blondish/greyish hair) and use a Kiki Milano eyebrow pencil in taupe, I think, which is very good but not that long-lasting. I'm on hols this week and would like something that doesn't wash off that easily when I swim - are the Maybelline Tattoo ones any good? Any other recs for a pen or mascara-type stuff that stays put?
