The Microsoft Natural Ergonomic Keyboard 4000 is an iconic, wired USB ergonomic keyboard renowned for its split‑key layout, distinct center wave, and cushioned palm rest designed to reduce wrist strain and prevent carpal tunnel syndrome.

Because Microsoft has officially discontinued this line, finding a pristine, unused unit in this condition is becoming incredibly difficult!

Condition Notes:

• Keyboard Status: Pristine and unused. Zero shine on the keys, zero wear on the wrist rest, and the cord is still neatly bundled in its factory tie.

• Packaging: The original retail box has been opened and shows minor shelf/storage wear, but it has completely protected the keyboard inside.

• Included Items: Comes with the Microsoft 4000 Keyboard and the detachable front raiser/lift stand. (Note: The original paper manual/documentation is not included).

Item will be securely packaged inside a shipping box to ensure the original retail packaging does not get damaged during transit. Fast handling time! Please look closely at all photos before purchasing. Let me know if you have any questions. Thanks for looking!
