Antique one-sho masu, five-go masu, and one-go masu. They are quite old and are antiques themselves. The construction is also very solid. The four corners are joined with a mortise and tenon joint, and the top has iron frames to prevent chipping for accurate measurement (one-sho masu and five-go masu). The bottom boards use bamboo nails, making them authentic and likely quite valuable. They have a refined look. There are stains and scratches, but how about it for antique lovers? They can be used as small item containers, interior decorations, and of course, as masu. Please check and understand the images.
