This binder is easy to use and cute. It has holes for attaching keychains. The clear cover makes it easy to see the stickers inside. The refills are pocket-type, so you can put in not only sticker backing sheets, but also trading cards and photos. When using it for sticker backing sheets, you can stick both thick and thin stickers beautifully. For inspection, we have opened the binder to check the binder hardware and button closure. Set Contents: Main binder (silver) 10 clear refills
