This is a used item, but it has few scratches and stains and is a relatively clean product. It is a set including the main unit and a USB cable. Operation has been confirmed. Thank you. This model commemorates the 5th anniversary of Hatsune Miku's birth, featuring an original design drawn on the back of the "Walkman" S series. Sony will release the "Hatsune Miku 5th Anniversary Model," which features Hatsune Miku's character design on the "Walkman" S series and is engraved with a serial number. The compatible models are the "NW-S764" (blue), "NW-S764" (black), and "NW-S764K" (blue), with a limited production of 3,939 units for each model. It seems to be a valuable item. How about it as a collector's item?
