Now sold separate for an extra cool cover you can use during different times of the year. Or just while the other one is washing. These covers are for the corn bag hot packs. These are just the covers and do not come with the actual corn bag. Corn bags can be found HERE. It’s a slip on cover so that the corn bags purchased on this site can easily be put into the covers. I only have a limited supply of each material. Right now I have lots of Christmas colors as we are entering the cold season which makes these covers great gifts for extra covers.
