This unique two piece set includes an attractive dome lid and removable freezer pod. Simply place the freezer pod in the freezer until you are ready to use it. Then, screw the pod into the lid and place the lid on a salad bowl or appetizer tray. The cold air from the freezer pod will descend down into food keeping it chilled and fresh. The universal lid design fits all 9-inch to 12-inch round bowls and trays. BPA-free polycarbonate. Bowl not included.
