● Size: S, for right hand ● Contents: Mouse body, receiver, Type-C cable ● Condition: Opened, no operational issues. I connected it to a computer and used it for a few minutes, but the size didn't fit, so I'm selling it. ● The outer box is double-layered (Japanese box inside an English package). There is a slight tear in the opened part. ELECOM EX-G PRO S size silent wireless mouse, Bluetooth and 2.4GHz wireless compatible, rechargeable, 8 buttons, high-speed scroll, tilt wheel, antibacterial, black M-XGS50MBSKBK The "EX-G" series of mice, co-developed with an orthopedic surgeon, allows you to use the mouse while maintaining the natural shape of your hand. In addition to 8 buttons to improve work efficiency, it features a tilt-compatible smart high-speed scroll, multi-connection for up to 3 devices, and a rechargeable battery, making it the PRO model with the best functionality in the series, in S size. The 8-button mouse "EX-G PRO" achieves the ultimate grip and the best functionality in the series, co-developed with a doctor. With the cooperation of Dr. Ichiro Miyakawa, Director of Narashinodai Orthopedic Clinic and Internal Medicine, we focused on the "brachioradialis" muscle that moves the wrist and the "extensor digitorum" muscle that moves the fingers, and pursued the angle and shape suitable for the muscles of the hand that move the mouse. Because you can simply place your hand naturally on it, you don't need to apply extra force, and it achieves a comfortable feel that minimizes the strain on both the wrist and fingers. To achieve a "feeling like you're not even holding it," we've adopted a design with rounded corners and seamless construction. In addition, we aimed for an even more evolved grip, such as a seamless operational feel that makes it easy to access each button.
