Thank you for viewing! This is a set of two textbooks with DVDs. "Revised DVD-Based Sign Language Textbook: National Sign Language Certification Exam, Grade 1 and 1st Grade Equivalent" National Sign Language Training Center Price: ¥3600 "Third Edition DVD-Based Sign Language Textbook: National Sign Language Certification Exam, Grade 2" National Sign Language Training Center Price: ¥3400 ◆ There is a faint stain on the back of the Grade 2 DVD that is not visible in the photo, but upon inspection, it does not appear to affect viewing. ◆ In the Grade 1 and 1st Grade equivalent textbook, there are faint pencil markings on a few pages of the sign language vocabulary section at the end of the book, but they have been erased with an eraser and are barely noticeable unless you look closely. Also, there are three pages with small animal index stickers. I have decided to leave them as they are, as removing them might tear the pages. ◆ These books have been used for study, so there are minor scratches on the covers and folds in the covers.
