Wireless Trackball Mouse Logitech ERGO M575SP Purchased in March 2025. Domestic genuine product. I opened it, but it didn't fit my hand, so I kept it on my desk without using it. The box has traces of tape being peeled off, but I kept it, so I will wrap it in cushioning material and ship it together. Ergonomic design black trackball mouse with a blue ball. - Brand: logi - Color: Black - Type: Trackball - Features: Ergonomic design - Number of buttons: 3 - Ball color: Blue Thank you for looking.
