This is a set of "Meimon no Mori" (Physics textbook), 2nd edition. It's the 4th revised edition. Brand new and unused. I purchased it last year (2024), but I never used it and stored it in a dark place. I'm selling it because I have no use for it. There are almost no noticeable stains, and it's in relatively good condition, but please refrain from purchasing if you are concerned about minor scratches or wrinkles (although I don't see many). Retail price is 1210 yen. Total 2420 yen. Immediate purchase is available, and no price reduction is possible. Please consider it. Physics Textbook
