Too Cool for School Shading

This is a shading product I have been using a lot for several years.

I bought the brush package, so I'm really enjoying using the dedicated brush haha. When I'm in a hurry, I use this to finish my jawline, nose contouring, and even eyeshadow all at once haha. It's also great that there are 3 colors~

I should try the Too Cool for School highlighter next time.

What kind of contouring product does everyone use?
