Aria flat mandolin AM-20. Sound is OK, with some age-related wear and tear on the exterior, but generally in good condition. Here are the specifications of this mandolin: ■ A-style flat mandolin ■ Top: Spruce ■ Sides/Back: Mahogany ■ Neck: Mahogany ■ Fingerboard: Ovangkol, 20F ■ Bridge: Ovangkol ■ Hardware: Chrome ■ Includes hard case ※ Please note that the materials used for the body, fingerboard, etc., may vary depending on the production period, so consider this information as a reference only. This is a current model, so you can buy it new. Currently, it's sold online at soundhouse for 23,400 yen, including the case. Instant purchase is welcome. When shipping, I don't have a suitable box, so I plan to wrap the hard case securely with bubble wrap. Thank you.
