Thank you for viewing. This is a wireless mouse from Logitech. During use, the Bluetooth/USB connection sometimes drops or stops working, so it does not operate stably. Therefore, it is listed as a "junk item." The exterior has no noticeable scratches or stains and is in relatively clean condition. We hope you can use it for repairs, disassembly, parts replacement, or practicing electronic work. *Please confirm the following: • Not suitable for normal use. • No operational guarantee or returns. • Batteries are not included. [Shipping Method] Shipping is planned via Yu-Packet Post, etc. We look forward to your purchase if you understand the above.
