I swear by these things! Each sheet is made of a thin, blue material. Almost plastic-y. But all I have to do is touch the sheet to my face and the shine is quickly absorbed. I simply pat one sheet all over my face and throw it away. No fuss, no muss. The only problem I have with them is the price - a little steep for only 50 sheets (I'm a cheapskate). But it's worth it to have a shine-free face without caking it with powder!
