Wired curved keyboard: the key area follows the movement of hands and fingers, and the wrist rest padded with memory foam and PU avoids pressure points. It has 106 + 3 keys, three feet to raise the front, a 1.8 m USB cable and measures 456 × 217 × 35 mm. A Spanish layout version exists (JK-4500ES-2).
