A deliberate 70 mm width encourages your fingers to spread naturally for lateral stability, while leaving you free to shift your grip forward or back and change your finger angle.
01 / WIDE BY DESIGN
A wider stance
The shape encourages the thumb, ring finger and little finger to spread naturally, with the aim of reducing lateral wobble through the shell itself.
02 / NO WAIST
No defined waist
Straight sides leave room to move the mouse forward and back within your hand, rather than locking you into one grip position.
03 / LOW FRONT
A lower front
A low front brings your fingertips closer to the click surface without restricting fine forward and backward movement.
LIGHTNESS BY STRUCTURE
Lightness, built into the structure.
Ribs reinforce the areas that bear load, without separate reinforcement parts. The assembled mouse measures approximately 30 g with the OP1 8K v2 PCB and other components installed.
