[New design specialized for gripping] A completely new design specialized for gripping while incorporating the philosophy of the previous XM shape. The sides are flat rather than inverted, allowing you to hold your fingers in any way you like without having to place your fingers in a fixed position. Additionally, the shell extends to the side of the main button, making it easy to place your finger on the right edge without worrying about accidentally clicking it.
"OP1" is a wired model of the previously released wireless mouse "OP1we". The weight has been reduced to approximately 50.5g, the sensor has been updated to PixArt's latest PAW3395, and the main button is equipped with a Kailh GX mechanical switch.
