Vintage Charm Harp 15-string lap zither. It was made in Japan in the 1950s or 1960s by F.M.T. and features a unique wavy wood frame and a figure-eight sound hole.
Regarding condition, it is 100% fully strung with all 15 strings intact, which is rare for these vintage models. The body is structurally solid but shows normal vintage surface wear, including a small chip in the wood on the bottom-right wavy edge. It is being sold as the instrument only, without the original box, pick, or paper song sheets.
