Thank you for viewing. This is a wireless mouse from Logicool (Logitech). It sometimes stops working or loses its Bluetooth/USB connection during use, so it does not operate stably. Therefore, I am selling it as a "junk item." The exterior has no noticeable scratches or stains and is in relatively good condition. I 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.
