Rainbow Glass teal stopper 11”

This stopper appears to be from the sixties, based on the research I’ve done. I don’t own the decanter and while I do collect them, I’d rather sell this one now than commit to finding its matching bottle. The base of the stopper has some damage but you wouldn’t see it while it’s in the bottle. The rest of it is in great shape. This stopper is HUGE. See photos for measurements. It is 11” long and about 3” at the widest point. Experienced glass shipper!
