I love these! I can get quite shiny by mid afternoon, but I hate layering on more powder. I can just use one of these sheets, and the shine is gone! It doesn't disturb my makeup, which is a major plus. The sheets are hard to describe, they are blue, have no powder stuff on them (yay!), are kinda like thin, flimsy plastic, and turn clear where they absorb oil. Perfect for back to school!
