great at taking away any shine/oil on my face, and do not disturb your makeup at all. you get 100 sheets for $7 ~ a pretty good value imo.
I have never used blotting papers before these from Sonia Kashuk. They are great! They absorb oil and persperation well, but leave makeup behind. I use it on my nose, cheeks, forehead, and chin. It is a large sheet. Probably about the size of a 3.5X5 photo. Also, they come in a plastic case, so they are protected while in my purse. I will repurchase. Similar products are more expensive.
Update: Just used one again after a warm summer shopping trip with the kids. These things are great! My makeup looks like I just applied it. All I did was press these against my face, and then reapply a bit of powder. Looks great!
