This is a set of 25 books from May 19, 2023 to May 17, 2024, plus the President's Choice "Amazing Company Mottos of Top-Class Companies That Ignite You With Just One Word." I purchased these new and have only flipped through them. They have been stored on a bookshelf since then. Some have been stored for a longer period, so please understand that these are used items. Thank you for your understanding. No individual sales or price reductions. Instant purchase is welcome.
