"New Course Chart Style Basic Mathematics C" Price: 1400 yen + tax This is a request from my son. He bought it but apparently never opened it. Although it is new, there are slight creases and scratches on the corners, so please check the photos carefully. It's barely noticeable at a glance. Due to the thickness, I will waterproof it with something like a Ziploc bag and ship it in an A4 envelope to save on shipping costs. Please note that I will not use any cushioning material.
