I am selling this item because I no longer have the opportunity to use it. It has been stored in a dark room and in a case. It's lightweight and folds up compactly, so it won't be a burden when carrying other luggage or instruments. I think it's an easy-to-handle item that you can easily take to live performances, concerts, studios, etc. It has pitch markings, making it easy to use for beginners. Size: Approximately 57 x 32 x 4 cm (when open) Weight: Approximately 2kg Includes: Main unit Storage case Mallets This is a set of 3 items. There are minor scratches from normal use, but I think you can use it without any problems for playing. Returns and exchanges are not accepted due to the buyer's circumstances. Please check the condition in the photos and purchase it as a used item. If you have any questions, please ask in the comments!
