I have never tried them because I hear they are not good. The brushes though have rocked my world. I even recommended them to Hooka, who went out and bought some.
I use an elf palette from time to time. A lot of the colors have glitter, which I loathe, but there are also many straight solids I like. For $5, if nothing else, it was worth playing with.
