This stays on well and it is waterproof for sure; I went swimming for 2 hours and it didn't budge an inch. The grey colour works well with my black hair. Love it!

There are tons of eyebrow products on the market and I return to this pencil often. It looks like an actual pencil when you first purchase it. The pencil works with your own oil in the eyebrow hair to create a very natural looking brows. While it is on the expensive side ($24) it lasts a very long time. I use short strokes to fill and color my brows. Shu Uemura will sharpen this pencil for free if you bring it to their counter.
