This is a Headway HCF505. It appears to be the successor or a higher-end model to the HCF18 and HCF 35 series. There is a dent on the top, but there are no problems as an instrument, and it is in very good condition. It's a flat-top guitar, but the back has an arch, so please consider it if you are interested. To my ears, the harsh metallic sound is suppressed, and it sounds mellow and smooth. I think it's suitable for those looking for a gentle tone. It will only be listed on Mercari.
