If you've ever been into natural, yet bushy looking eyebrows, you must have seen brow pens gaining on popularity. I think one by Glossier is especially popular. I've wanted one of these super precise brow pens, because I thought it would make my brows look thicker, yet still natural. Sometimes regular brow pencils can look unnatural and too harsh.  However, it seems hard to one that is well saturated and has fine enough tip to look like realistic brow hairs.
