These are the thing to buy "someone who has everything". These are a set of four vintage 1960s matching silver-plate drinks coolers. You would freeze then and when they get very cold - you pop in a glass with your cocktail and use each cooler as a swizzle stick to keep your drink nice and cold. They do not contain ice - so would not be watering down your drink.
They are wonderful pieces of minimalistic Danish design. They were made by Asba, Denmark and designed by the celebrated poet, mathematician and inventor, Piet Hein.
They are stamped Epns Absa Denmark. Each cooler is in excellent condition - and they are highly collectable pieces of Scandinavian mid-century design.
Each one is just over 6 inches in length with a diameter of the ball section at just over 1 inch.
