This is likely a ceramic piece by the artist Satoshi Watanabe. (Uncertain as there is no receipt, estimated from the signature on the back of the plate.) It's a considerably large and thick ceramic square plate. I think it can be used as a serving dish for entertaining or as a work of art. I'm selling it because it's been stored away and it's a waste. No box (will be wrapped in bubble wrap and shipped in a cardboard box) Size: 26 x 26 cm Plate thickness: 1.5 cm Foot height: approximately 1.5 cm --- Material: Pottery/Ceramics Shape: Square plate Item Type: Large plate Style: Japanese Ceramics Ceramic art Fine art Antique #kinako_management_tag_tableware
