Suzuki mandola, No. 501, made in 1963. The pegs turn smoothly, and it can be tuned, but there are cracks in the paint due to aging. The strings are new, so I think it's fine for practicing at home or playing for fun, but it's not an instrument that can be brought to a concert without adjustment. Therefore, I would consider it a junk-level instrument. It's a bit larger than a mandolin and has a strong presence, so I think it can also be used as an interior decoration, allowing you to easily make sounds.
