Convenient and economical, the Dékor refills are easy to use and offer great capacity, holding up to 40 diapers each and 422 per refill. Note: These refills will fit all "regular" size Diaper Dekor pails. They will NOT fit Plus sized pails. The size refill you need is determined by the size of the pail. This can be determined by viewing the label on the inside of the door of your pail. Note: Refills are not interchangeable between Plus and "Regular" sizes
