Vintage Jadeite Glass Hexagon Drawer Door Knobs

Nice set of vintage jadeite green glass drawer or cupboard door knobs in a fun hexagon shape. Silver tone screw and bolt as shown. There are six knobs but unfortunately one has a crack and silver scuffs that looks like they were left by metal or paint. Please see all photos. Other five knobs are in good vintage condition with no issues. Knobs measure about 1" x 1" across the top and 1 1/4" high -- the glass section only.
