While this eyebrow pencil is sufficiently resistant to rubbing and sebum, it's a bit difficult to use. Because the packaging is all pink, it's hard to tell at a glance which is the brush and which is the pencil. The white pencil and brush marks on the back and the slightly longer cap on the pencil side make it easy to tell the difference, but there's a slight lag when you're in a rush in the morning. The round tip makes it a bit difficult to draw thin lines. The brush is also hard, and even without applying any pressure, it hurts. The color is listed as gray, but it looks more like a dark brown. CEZANNE's Natural Gray looked more gray to me. I was satisfied with the smudge-proofing, but overall it was a questionable pencil. I recommend checking it out in store before purchasing.
