Thank you for viewing. This is a GEMINI CDM-4000. Please check the photos for some damage. The power turns on and I have performed all basic operations, but I have not tested the USB functionality. CD playback works without any problems. 【Notes】 ※ I cannot answer questions about the purchase date or frequency of use, as this is a used item. ※ The photos were taken with a smartphone, so the actual item may look slightly different. ※ There may be scratches and stains that are difficult to see in the photos. ※ I do not smoke. ※ Returns are not accepted after evaluation (including to prevent product substitution).
