These Korean glass Go stones, 7 x 20,5 mm, have a slightly smaller diameter as the usual 21,5mm-stones. In addition does this set not contain the usual 180 stones but only 160 stones per color. While most Go games have less than 300 moves, this amount of stones can absolutely be seen as more than sufficient. These stones convince with a good quality and are delivered in an attractive plasticbox and have a very attractive price.
