[▼Product Description] From Logitech's ergonomic design series, the ERGO M575 wireless trackball mouse. It features a unique shape that reduces strain on the wrist and arm, providing comfortable operation even during long hours of desk work or telework. The trackball is operated by the thumb, eliminating the need to move the mouse itself, making it suitable for space-saving desk environments. The trackball has been replaced from the standard blue color to silver, giving it an appearance that naturally blends into white-based interiors and desk environments. The original blue ball is not included. Operation has been confirmed, and scrolling and clicking operations are also problem-free. Accessories such as the outer box, instruction manual, and receiver are all included, allowing for immediate use upon arrival. This is a perfect mouse for those looking for a balance of practicality and design. [▼Brand (Manufacturer)] logicool / Logitech [▼Size] One Size *Standard size based on manufacturer specifications.
