A pair of containers, provide complimentary outer surface contours so as to be mutually engagable in intimate nesting contact. Each of the containers provides an outwardly extending embossment and an inwardly extending groove. The embossment of each of containers is positioned and sized for frictional engagement with the groove on the other of the pair of containers for mutual securement of the containers when the containers are nested, thereby enabling the containers to be engaged and handled as a unit while dispensing different materials.
