Grid notebooks, 15mm x 3 books, 12mm x 3 books, a set of 6 books in total. I'm selling these because I bought too many and couldn't use them all. How about them for the new school year? They are new and unused, but the corners are slightly scuffed. Please check the photos. I have stored them at home, so I would appreciate it if you could understand. Thank you for your purchase.
