We've seen quite a few brow pens recently, which are felt-tip makeup markers that allow you to draw on tiny little strokes to mimic the look of microbladed brows. However, we've never quite seen anything like the L'Oréal Paris Unbelieva'brow Micro Tattoo Brow Ink Pen (£10), which features a very unusually-shaped tip, which the brand calls a "micro-trident" and to us looks like an itty-bitty bread knife. Either way, the tiny little teeth were designed to mimic the microblading application technique, resulting in groups of finely-drawn lines that resembled brow hairs. Comb the notched side through yoru brows, then you use the very tip of the pen to do any detail work on areas that need more precision. Our only gripe? We wish it came in a few more shades that were on the ashy end of the hair-colour spectrum.
