Corning Ware Forever Yours Lasagna Pan. A very hard to find piece in this pattern of Forever Yours from Corning Ware. This is for a 12 x 11 in. x 2.5 in. deep lasagna pan. This size is hard to find and this pattern is especially hard to find. It matches the Corelle dinnerware of the same name. This piece is used and near mint. Super nice.
