Concave non-slip side skirt: The wide left wing and concave left side offer good thumb support; the left and right side skirts use hole texture technology and are molded together using injection molding, which has an air permeability and perspiration effect and improves anti-skid performance. Separate primary keys on the left and right: The left key, roller, right key, and back cover are the four sections that make up the mouse's upper portion. The upper surface's separated design reduces structural interference, improves left and right key force uniformity, and speeds up click operation.
