The present invention relates to dispensing cartons for sheet materials such as polymeric sheets, metallic foils, and other sheet materials, particularly those suitable for use in the containment and protection of various items including perishable materials. The core particles consist of TiO2 or metal salts of the form M1xM22-2xTiO2 where M1 is selected from the group consisting of Ba, Sr and Ca and wherein M2 is selected from the group consisting of Rb, Li, Na and K. The cutting guide is then aligned using the pins, and bone of the joint is cut, using the guide, in preparation for an implant operative to replace a portion of the joint. The apexes in each bead portion having the same radial height, as measured from a bead base line.
