This is a NIZ electrostatic capacitive keyboard. It has a US 84-key layout with a 35g actuation force. I purchased it a few years ago and used it for work for about six months. It has been sitting in storage since I switched to a different keyboard. I am selling it to organize my equipment. The condition is good, with no noticeable scratches, but there is some minor dirt. Included accessories are the receiver, USB cable (A to C), keycap puller, replacement keycaps, springs for adjusting the actuation force, and the Japanese instruction manual. It will be shipped in its original box, inside a cardboard box.
