Replacement trackball for perrix, green. Perfect for adding a touch of color or changing the look of your 34mm trackball mouse, such as the MX Ergo or M575. - Diameter: 34mm - Weight: 30g - Brand: perixx - Color: Green Purchased about a year ago, used for 1-2 months, then replaced with a different color and stored at home (non-smoking environment, no pets). Due to the short usage period, there are no noticeable scratches and it's in relatively good condition, with no operational issues. However, it is a used item, so please check the images before purchasing. Please refrain from purchasing if you have any concerns. Please note that we do not offer discounts.
