⭕️ I do not accept requests for price reductions. ⭕️ 【Important】There are notes like "This will be on the exam." Because it's a Frixion pen (erasable pen), I will erase the writing before shipping, but there may be some that I miss due to the large number of pages. As shown in the photos, there are parts where the box is torn, and other oversights. Please purchase only if you can agree to the above. This is a textbook purchased at a 129,000 yen training course.
