① Hell Mechanical Training Phrases: Super-Speed DVD Edition - ¥1,800 ② Hell Mechanical Training Phrases: Rampaging Classical Masterpieces Edition - ¥1,600 By Shinichi Kobayashi The condition is extremely clean, with only minor folds due to aging. The CDs and DVDs are unplayed, and the sealed sections are unopened. At the time, I bought these to master the guitar, but they were too difficult, and I closed the books immediately and stored them for a long time, lol. I will put them up for sale as I don't plan to use them in the future. I will sell them to anyone who needs them.
