Thank you for viewing. This is a flat-backed mandolin by MAVIS. It's the type of mandolin with a flat back. The F-holes are stylish. It's well-made and recommended. There are some scratches and dirt from use, but I think it's in good condition. I'm not an expert, so I don't know the details, but it can be played normally. Body only. For those who understand the condition, thank you.
