Lune Liner - Cuivre 29

The way this shifts from copper to gold depending on the light is mesmerizing. I used it for a thin wing and it stayed put through a long workday without smudging.

The ultra-fine tip makes it so easy to draw a crisp wing without any mess—the color really does shift in the light. I was surprised how smoothly it glided on and stayed put all day without fading.
