I'm not sure how old it is, but I think it's quite old. It's well-made. I heard that it was used at my parents' house to measure rice in the past. The corners are worn and rounded, and there are scratches all over. It seems to have been used for a long time. What appears to be the heads of the nails used in the assembly are slightly protruding from the bottom (last photo). It's an old item. How about it as a collectible?
