Elementary School Entrance Exams: Perfect Thinking Problems - Set of 4 Books Price: ¥2200 (tax included) x 4 = ¥8800 I purchased these for the entrance exams of prestigious elementary schools. Book 1: All pages were cut along the dotted lines and copied for use. No writing. Book 2: Problems up to number 6 were cut and copied for use, but the rest were not used. No writing. Books 3 and 4: Brand new and unused. Recommended for those who have already done various practice papers, as these papers have a slightly different approach, making them great for test preparation. Priority given to those who purchase immediately. No price reductions or holds. Please understand that these items have been stored at home and are inspected by a non-professional. Returns are not accepted as the books are usable. Thank you.
