lot of assorted glass bottle & decanter stoppers, old, antique, vintage

Collection of six unusual decanter bottle stoppers, all solid glass except the bubble shaped stopper colored depression pink.

The pink stopper measures 2 3/4" across the ball, the blue stopper measures 3" long end to end, and the largest of the clear crystal stoppers measures 6 3/4" overall.

These are mostly ground glass fitters, they have some maker's flaws (roughness to the edge) as is common with these pieces.
