In this macro shot of my (very dry) hands, you'll notice what I'm talking about when it comes to the tip of this pen. You need to use a very gentle motion for the most natural look, bouncing and flicking lines on your brows on the diagonal (so all three tips hit, yet barely touch, your skin). If you press down even a little, you'll get the bottom result vs. the top one.
Now some spots are a bit fuller than I'd like in my pictures (which I took on my first try) but, once I practiced on my hand, I got it right from there on out. It may sound like overkill now, but I'd absolutely recommend testing the pen out on your own hand first so you understand the pressure and angle that will achieve the desired final look on your face.
