I purchased this about a month ago and used it once or twice, but wired mice don't suit me, so I've been storing it. I'm currently using a wireless mouse for work as a substitute. I think the usage time was about an hour and a half. It's almost like new, but please understand that it has been stored at home. I bought it on Amazon for a little over 10,000 yen. All accessories are included! Shipping included, will ship the same day (^-^)
