Autumn Warm Tone PIPL Doll Highlighter

I've seen thick pens on Chinese Instagram that have a highlighter on one end and a contouring pen on the other... (Does anyone know what that is?) I found this highlighter while searching for that. I like eyeshadows with shimmer, and since the PIPL highlighter also has a pearly finish, I use it a lot. I'm using it on various parts of my face, like my nose and under-eye area.
