I got this from suzykirei. It's hygienic to use tweezers to take them out. They're plastic so they're hard to grab, but it's better than sticking your fingers in to take them out. There's no weird smell. I don't get any acne or rough skin from using them. The sheets are thin, but they're soaked in beauty essence and keep my face moist. I think 10 minutes is just right. I use a hair dryer while I'm using it so it dries out easily. My skin feels moisturized afterwards too, which is nice.
