These are old books, a hobby of my father's. I was going to get rid of them, but since it's the Mercari sale period, I can save on shipping, so I'll list them. I will delete the listing when the period ends. The condition isn't great, and they've been sitting on a bookshelf for a long time. Please purchase only if you understand this. Regarding shipping, it usually takes 1-3 days depending on the situation, but occasionally it may take 5-6 days.
