This belonged to my grandmother. There's a crab on it. I don't know its value very well, but I'd like to pass it on to someone who will cherish it. It has a case, but the clasp on the lid is loose (photos 4 and 5). There's a note that says "A-157" on it, possibly a size (photo 3). I heard it cost 200,000 yen when it was purchased.
