A bundle of welding electrodes or rods are confined within a substantially rigid cylindrical tube of extruded plastics material, and each end portion of the tube receives a cylindrical cup-shaped body of an end closure member molded of a more resilient plastics material. The body of each closure member is slightly larger than the inner diameter of the tube and is press-fitted into the tube to form an air-resistant seal with the tube. Either closure member may be removed by pulling the body from the tube or by impacting the body with the welding rods within the tube, and each closure member is reusable and resealable with the tube.
