This set of go stones and go bowls was acquired from an art dealer in Kanagawa.
The bowls are Mikura Island Mulberry. For reference, Mr. Kuroki carries them for about $1900 new (currently sold out). They are in very good physical shape but their shellac finish has serious issues. They should be cleaned with a varnish stripper, then re-finished (if it was me, I'd do an oil and wax finish as per my Care Instructions).
The stones are slate and shell size 36. There are 179 black pieces at 10.3mm, with one chipped. The white pieces are 9.9mm and count 180 with 2 chipped. 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. The white stones are in need of a good cleaning, but appear to be mostly moon / snow grades.
Please contact us if you would like to bundle this set with a board.
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.
