I'm selling these because I realized I had accumulated them. They have been used. How about using them to study for entrance exams or qualifications? You can purchase them starting from 2 sheets. They are red sheets, so I don't intend to reinforce them, but I can reinforce them for an additional 200 yen if you wish. The number available may have decreased. One sheet is 200 yen. Price reduced!! 2000 yen → 999 yen
