This set came to Baduk Club from a reseller in Yokohama City. Agate and Onyx are a popular choice in China, where this set probably came from originally.
The white pieces are agate, with some variance in color. The black are onyx. They are about size 36 (10mm) thick, but will have some variance in size because such stones cannot be cut with as much precision as slate & shell. They were not counted, but they fill the bowls very snugly so it is likely a complete set.
The go bowls are Marble, with nice lids cut to match. They are polished on the outside but may be rough on the interior - see the photo with lids for details.
The set includes a red storage box, but it can be discarded if you don't want it.
This is a Vintage product.
Shipping Details:
FedEx International Priority shipping from Japan is already included in the purchase price. It is possible to downgrade to Seamail shipping to save about $80, but you will need to contact us to request this (the risk of damage to the bowls would be high). In either case, please allow a week for packing and customs, then we will provide a tracking number from the shipping service that you can use to sign up for notifications.
