Please understand. Notes: The answers and explanations have been removed from the textbooks in photo 4. There are a few pages with writing that could not be erased, as shown in photo 5 and later. There is writing on about 1/4 of the pages in Kanji Plaza. There are also some answers written on the answer sheets. Please consider purchasing if you understand the above. Even if you are in the middle of a conversation in the comments section, the person who purchases the item first will be given priority. Thank you for your understanding.
