Vintage Fenton cranberry opalescent hobnail salt pepper shakers

These shakers are approximately 3 1/4 inches high with metal lids. They were blown in a mold and have ground mouths. One has the blue Fenton worker label. They were used and the lid to the salt has a little corrosion inside, and some bumpiness to the metal plate loss in spots around the outside of the lid. Not all the hobnails in the salt are opalescent. The glass has no chips or cracks, and despite the wear to the salt lid (which can be replaced), this is a collectible and increasingly hard to find shaker set.
