Thank you for viewing. This is Yotsuya Otsuka's drill, "One Step Ahead: Leader Drill, Grade 2 Calculation." I bought it for my child, but we didn't have a chance to use it, so it has been stored at home. 【Condition】 ・Brand new and unused. ・I have confirmed that there are no writings or page folds. ・Since it was stored on a bookshelf at home, there may be slight scratches on the cover. I think it's a great deal for those who don't mind. 【Product Features】 ・This drill is well-regarded as preparatory study for the "Yosyu Series." ・It is ideal for "advanced learning" that is a little ahead of school, and for building basic skills in preparation for junior high school entrance exams. ・It also includes "explanation advice" for parents, making it easy to teach. 【Shipping】 It will be placed in a water-resistant OPP bag and shipped in an envelope. We will ship via anonymous delivery. Immediate purchase is welcome. How about establishing a daily study habit? Thank you very much.
