Thank you for viewing. This item is being sold due to the year-end cleaning and decluttering. I purchased it as a spare wireless keyboard and mouse, so it has been stored with little use. I tested it for functionality before listing, and there were no issues. Cancellations and returns are not accepted after the item has been shipped. Please purchase only if you understand that this is a used item.
