High-Grade Model Thumb-Operated Trackball Mouse "Elecom IST PRO" This item was purchased from Yodobashi Camera on February 2, 2025. It comes with a 2-year warranty from the date of purchase. The warranty card will be included. I am selling this because it didn't fit my small hands. I only used it for about a day to try it out. Overall, I think the condition is good. However, please understand that this is a used item before bidding. All accessories are included.
