This set of go stones and go bowls was acquired from an art dealer in Kyoto.
The bowls are quince, sometimes called Indian Rosewood. They are in very good shape, with almost no wear on the underside.
The stones are slate and shell size 31, with 180 pieces of each color. The white stones are about 8.3mm, the black around 8.6mm. It is very common for the black stones to be thicker - if both colors are the same size, then the bright white pieces will appear larger.
Seamail shipping to the US from Japan is already included in the purchase price for free - however, this service takes up to 2-3 months. You may upgrade to FedEx shipping for a $70 fee by contacting me - this reduces the shipping time to only 5 business days. In either case you will have a tracking number from the shipping service that you can use to sign up for notifications.
Please understand that this is a vintage item, so it is sold in an as-is condition.
