I'm not certain what these were made for - someone said maybe a Knife rest? They measure about 4" in L from the metal ball end to the end of the cut glass crystal ball. The metal has an uneven finish - I'm not sure why. The end balls are about 7/8" across - they are glued into the metal base. I'm not certain the age of these but were purchased with items dating from the 1980's - 1990's. I am selling 2 at a time. Please inquire if more are needed.
