I use it! I only use the blush, highlighter, and concealer. (I don't wear a lot of makeup to begin with). It gets tricky with all of the products cuz u can't mix/blend on shabbos. So shabbos eyeliner and shabbos eyeshadow I like to stay away from cuz it's very hard to apply them both without touching.
People sell all over the place. Where do u live?
