① Winter Skills - Regular Price: 250 yen Includes Winter Challenge Kanji Calculations ② Winter 12 - Regular Price: 240 yen Includes Winter Confirmation Book ③ Energetic! Winter Drill - Regular Price: 220 yen ④ Step to Grade 1 - 240 yen ⑤ GO to Grade 1 - 230 yen This is a set of 5 books, equivalent to 1180 yen. They have been stored at home, so there may be some minor stains, but they are unused. They will be sent in an envelope without cushioning materials like bubble wrap. I am not considering lowering the price.
