These items were either purchased on Mercari or are used items that have been owned for several years. I read them once and then stored them on my bookshelf at home. Please understand that these are used items and may have yellowing due to age. *It's difficult to see the yellowing with a phone camera; please comment if you would like more details on the condition. Please understand that these items are stored and assessed by a private individual. No individual sales. I will respond as quickly as possible.
