Unopened. Set of 3 books. Please ask if you have any questions. ● Bulk purchases are welcome. In that case, we will deduct the duplicate shipping costs, so please let us know. ● Because we are also using other sites, the listing may end without notice. ● Seasonal items and items with low prices are scheduled to be listed for a short period. We may remove the listing and dispose of the items. ● Please note that we frequently cancel and relist items. ● Immediate purchase is welcome. However, we will assume that you are satisfied with the condition, so we will not accept any complaints afterward. Please be sure to check anything you are concerned about before purchasing. ● We accept price negotiations (but we may not always be able to accommodate them). Since it's first-come, first-served, please understand that we are not responsible if someone else purchases the item during negotiations or after a price change.
