Thank you very much for viewing. I purchased both the upper and lower volumes here, but I ended up not using them. I'd like to offer them to someone who can make use of them in the condition I received them. Upper Volume: Although this item has hardly been used, it had a name written on it, which was erased with tape before being given to me. Lower Volume: This item has writing in about 20% of it. The seller erased the writing made with Frixion pens and pencils, but there are some writings that couldn't be erased, and there are also creases on the front and back covers. Neither book has a check sheet. For those who understand that these are home-stored and used items. I will inspect them carefully before handing them over, but there may be oversights. Please consider the above, and refrain from bidding if you are a perfectionist. No claims or returns, please. Thank you very much.
