Has anyone used the ‘Pigment Sticks’ (the oil painting crayons). If so, are they worth the price?

Hello strangers. Here’s a piece of art I’m working on.
Love youuuu🖤

I didn’t realize this had an app💀
Now I can actually use this. Lmao.

Okay, I’m still trying to figure out how to use this.

Hullo out there.
