I got into using picks only like 3 years after I first learned to play guitar and found them awkard. I was recommended to use really thin picks and I hated them. I started using really thick (2mm) picks and felt a little bit more comfortable. My main problem was that picks were slick and shiny and didn't sit well with sweaty fingers.
Then I found these picks, that not only are on the thicker side, but also had the sandy, powdery surface. It clicked with me.
The sand/powder wears off very quick which is a shame, but they still feel pretty textured after that.
