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.
