This vintage clear bubble glass holder is most likely an ashtray and is a unique piece that could have been used for various purposes as well such as holding trinkets, or candles etc. The heavy glass material and round shape give it a decorative appeal that would make it a great addition to any collection. I believe this to be an ashtray. It is perfect for anyone who appreciates vintage decorative items and wants to add a touch of elegance to their collection or use for whatever your choosing.
