Black and Tan 32 plastic DGT chess pieces boasting 3.75 inch king (base diameter 1.5 inches) with felted bottoms. The pawn base diameter is 1 inch. The pieces demonstrate beautiful workmanship, very stable on surfaces due to the wide heavy base and are made in China. The total set weight is 28 ounces. No extra queens but 2 additional queens can be added for extra fee. Please notice that the pieces (especially black pieces) might exhibit minor scuffs on their surface due to rubbing against each other during shipping. The scratches/scuffs don’t affect their beauty or overall quality. The last 4 photos show how this set compares to triple weighted pieces comonly sold nowadays. The set comes in a plastic bag.
