This lovely board is from a seller in Kanagawa with an immaculate reputation. It is a 5.5cm hagi board (4 pieces joined together), which is common for boards of this thickness to avoid the warping that will occur over time with a single-piece board.
The grains are lovely, and look like textbook Kaya. The corners and edges look great. There are some marks, mostly on the underside. Kaya is very dense because it is a slow-growth tree, so it is not surprising that the board weighs about 6.5kg.
Please contact me if you would like to bundle this item with another order from Japan. Check my Colorado inventory for some spare legs (that is what the square slots on the underside are for) if you are interested in converting this to a floor board.
International seamail shipping from Japan (to almost everywhere) is already included in the purchase price for free - however, this service takes up to 2-3 months. You may upgrade to FedEx shipping by adding this upgrade to your cart. This also means your items will have more room for padding and spend less time in transit, so they are less likely to be damaged by the shipping. 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.
