Standing 20cm tall, this Uber Games Small Chess Set comes with (32) black and white, high density polyethylene chess pieces. Each piece has a base diameter of 7cm to 9.5cm and weighs between 60mls to 170mls. If you prefer to make the chess pieces a little heavier, you can easily add fine sand through the hole in the base. The chess pieces are made of rugged, waterproof, and UV-resistant injection moulded plastic. These are commercial grade game pieces and will stand up to years of abuse. They withstand the outdoor elements very well and will retain their colour. We have these sets in the heat of the Middle East, the humidity of the Far East, the cold of the Rocky Mountains and the salty air, sun and sand of the Southern California beaches. This Uber Games Small Chess Pieces set will inspire children to play!
