Thank you for viewing. ○ Logitech Wireless Keyboard K380 Purchased and used several years ago, but I am selling it due to a change in my work environment. ○ There are no noticeable stains, but there may be some wear and tear on the letters due to aging and use. Also, there is some dirt on the back and some scratches/tears on the outer box. Please refrain from purchasing if you are concerned. ○ Bluetooth connection is possible and there are no problems with the functionality. It will be shipped in the outer box, then OPP and bubble wrap. Connection type...Wireless (Bluetooth) Keyboard/Size...Tenkeyless Connection method...Bluetooth
