New, unused, and unopened. Stored at home, so for those who don't mind. The outer box has some stains. Since it's unused and unopened, I haven't checked the operation. Please contact the manufacturer for initial defects, etc. (No returns). I plan to wrap the outer box in air-cushion packaging and ship it via宅配便 (courier service). A 1TB external hard drive with a quiet design and excellent heat dissipation. - Brand: I-O DATA - Model: HDCZ-UT1KC - Storage Capacity: 1TB - Features: Quiet design, heat dissipation - Compatible OS: Windows & Mac Thank you for looking.
