This is a used item, but it runs smoothly. I purchased it from Murasaki Sports and used it for about six months. I apologize, but I often receive technical inquiries in the comments. However, as I am a beginner and this item was chosen by a friend, I am unable to answer most of them. Thank you for your understanding. Please consider purchasing. It has been used for a short period, so there are few scratches. Please check the photos and make your purchase after careful consideration and acceptance.
