Logitech Wireless Keyboard K275 Wireless Numeric Keypad Purchased in 2021. The keyboard is in good condition with no noticeable scratches, as I don't use the desktop much. However, the printing on the K and N keys is worn. Operation has been confirmed, but please understand that this is a used item before purchasing. Shipping may not have sufficient bubble wrap, so I plan to protect it with an alternative and ship it in a simple paper bag. Wireless keyboard with numeric keypad. The full-size space design with a wide curved space bar provides both typing comfort and space-saving. Connection supports Unifying USB, which utilizes Logitech's proprietary Advanced 2.4GHz wireless connection. Even in a wireless environment with a lot of communication, there is no delay or interruption in communication from up to 10m* away. Water-resistant design that can withstand up to 60ml of liquid (water). A battery life of up to 24 months is also a feature of this wireless keyboard. *Varies depending on the usage environment.
