Thank you for viewing. I purchased this new about a year ago to use at cafes and on the go. However, I couldn't get used to the operation and it didn't suit me, so I gave up after using it a few times for a short period. After that, it has been stored at home. I disposed of the outer box, but both the case and the main unit are clean and have hardly been used, so if you are looking for one or are interested, please consider it. I will wrap it in bubble wrap when shipping. Please rest assured. The packaging may separate the main unit and the case. Thank you for your understanding. #Mouse #Trackball
