Purchased around 2016 and used at work for just under two years. After changing jobs, I was no longer able to use a wireless mouse due to security reasons, and I've been storing it at home since then. In preparation for this sale, I wiped it down with an alcohol cloth and sprayed it with an air duster. Operation has also been confirmed. ■ Some images are borrowed from Amazon for illustrative purposes. Please understand that what is being sold is a used item.
