Gorgeous fumed bubble cap made by Soup Glass and Freeman Glassworks. This is a “Quadropal” design by Soup Glass, featuring 4 brilliant Gilson Opals! These opals shine brightly in the light and accent the cap well. The usual retail is $450 for the Quadropal style. It is 27.8mm and will work excellent with 25mm bangers! It is almost 2 1/2” tall and the nipple is 3/4” long. It has a flat top so it can also stand up with no problem. This one is signed, dated, and looking for a good home!
