This is Used Keyboard

The two-handed English Maltron fully ergonomic keyboard conforms to the natural shape of hands and varying finger lengths, reducing movement and tension. This design not only helps prevent the onset of RSI (Repetitive Strain Injury) symptoms but also aids in relieving existing RSI pain and promoting recovery.

Features:

The fully ergonomic design conforms to the natural shape of hands and accommodates varying finger lengths, reducing movement and tension.

Its split design eliminates wrist twist and includes a central number cluster usable by either hand as preferred.

Tilted keys and pads minimize downward movement of the palms (pronation), further reducing muscle tension.

Straight vertical key columns eliminate tens of thousands of finger and wrist twists over the course of a day's work.

Thumb keys for Space (as well as E on Maltron layouts), Return, Delete, Backspace, and Cursor keys decrease hand and arm movement, making use of versatile thumbs more effective.

Built-in large palm resting pads promote immediate hand and arm relaxation during "Thinking Time" and contribute to a reduction in arm rotation.

USB connector with approximately 2m cable included.
