Review title is Requires some effort for application but stays on pretty well..... [SEP] This is a pack of 2 mechanical brow liners in the color brown. These are dual ended pencils so one end has a brow brush while the other end has the eyebrow product. The pencils have a beautiful gold casing that is slim and comfortable to grasp. I think the formula is a little dry so I had to apply some pressure for the desired color payout. The fine tip allows you to draw in precise brow hairs. The staying power is great and held up well throughout my 8+ hour work day. I wanted to test out the waterproof claim so I did shower without washing my face and the color didn't really budge if left untouched. It came off easily using a makeup wipe.
