I have found these to be an everyday necessity! I keep one in my purse and in my car so I always have one with me. The sheets gently blot oil without messing up my makeup and the case has a large mirror inside for touch ups. The sponge is great so you don't have to handle the papers with your hands on your face. Another great thing that I just found recently is that there are actually 5 sheets of adhesive on the sponge so if it starts to be less sticky, you can peel off the top sheet for a fresh one underneath!
