Thank you for viewing. This is a trackball mouse for sale. I am selling it because my wrist, which was experiencing symptoms of tenosynovitis, has recovered. *No box or instruction manual included. I purchased and used it in 2023. I believe the condition is relatively good, but please consider this item only if you understand that it is a used product.
