This item was purchased in May 2025 from the Sanwa Direct Rakuten store. I am selling this because I purchased a Logitech trackball mouse. I have cleaned it as thoroughly as possible, but please understand that this is a used item before purchasing. Only the items shown in the photos will be sent. When I purchased it, I felt a strange sensation when operating the trackball, and I saw many similar reviews. I have modified it to feel normal by shaving down the plastic supporting the ball. Please be aware that this DIY modification has been done. ● I will ship within 24 hours of purchase (payment confirmation). If you have any preferred delivery dates or times, please contact me via the transaction message. ● I do not accept price negotiations. I regularly review and lower the price, so if you like, please "like" the item and consider it again when it reaches your desired price. ● I cannot respond to comments such as "It's cheaper elsewhere." Please purchase the item at the lower price. ● I do not hold items. I welcome immediate purchase without comments for all listed items. Please note that the first person to purchase, even if there are ongoing comment exchanges with others, will be prioritized. ● I may block users at my discretion to avoid transactions with those who comment without reading the product description.
