ERGONOMIC COMPACT DESIGN

The numpad-free compact layout saves desk space and lets you position your mouse closer to your body, reducing wrist strain. Low-profile scissor-switch keys deliver quiet, tactile feedback for fast, accurate typing—ideal for daily work/office use (not recommended for gaming).
