Hey are quite heavy with the kings and queens weighing in around 2.5 oz. The kings are just shy of 2 in height. The pieces are displayed on 1.5 squares, which I think makes a perfect pair (board for display only and not included). After exhaustive research I've been able to find out little else about this set, but it's a piece of art and a delight to behold.
