Folger's actually had some "printables" that were free to use to make them into cookie containers for gifts. I think Sondray posted it in the links and resources area awhile back. They were really cute. I wash mine out with smell iliminating dish soap. I think dawn or palmolive makes it. Can't remember off the top of my head. Or you can use some lemon juice, your regular dish soap and warm water. That kills the odor too.
