Thank you for viewing. Please be sure to check the profile. ・I am not an expert, so I cannot answer detailed questions. I will offer a small discount if you purchase multiple items. ・I do not mention yellowing or fading due to aging unless it is significant. Please check the photos. If you are concerned, please comment and I will answer. The assumption is that the used items are readable. ・If you have any other questions, please contact me before purchasing.
