This glass was manufactured by Cocktail Kingdom. It is a vintage style that was originally used at various Polynesian restaurants to serve the deep sea diver/skin diver/pearl diver cocktail. The glass has a rippled base (sometimes referred to as "ringed") and is topped with a champagne shaped bowl. It does have The "Beachbum Berry" logo on the base (visible the right way round as you drink - and backwards if you're examining it from the outside) and it comes nicely packaged in a colourful cardboard box. Measures: 4in (10.2cm) height x 3.5in (8.9cm) diameter.
