A 2026 edition reference book that addresses the three SPI test formats in order of frequency. ☆ Title: This is the Real SPI3! 2026 Edition ☆ Publisher: Kodansha I accidentally bought two copies of the same book, and this one has never been used since I purchased it. It has been stored on a shelf, but there are some minor scratches on the cover, so please refrain from purchasing if you are sensitive to such things. Also, please be sure to check my profile. Thank you for looking!
