Thank you for viewing. I purchased this for 4000 yen, but I haven't had time to look at it, so I've just been storing it. This is the original item, and I haven't used it. I will quote the comment from when it was listed: …………… Hama Gakuen Grade 5 Master Course Math V Class Exercise Print 2017 Academic Year No. 1 to No. 34 My child used this for entrance exam study. There are writings in it. The parts with names have been cut out. For those who understand that this is a used item, thank you for your understanding.
