The Lenovo 4X30L79912 Essential combo provides a reliable wired USB setup featuring a full-size membrane keyboard and a matching optical mouse. The keyboard is designed with low-profile island-style keys for a comfortable typing experience and includes a waterproof membrane to protect the internal circuitry from accidental spills. To help you find your ideal typing angle, it comes with adjustable feet, while dedicated FN media controls allow you to quickly manage volume and playback without leaving your current application. LED indicators for Caps Lock and Num Lock keep you informed of your current settings at a glance. Measuring 424 x 21 x 156 mm, the black keyboard is paired with an ambidextrous optical mouse that works for both left- and right-handed users. This mouse features a 1600 dpi resolution for precise cursor movement and three buttons, including a scroll wheel for easier navigation through long documents or web pages. Both devices are powered via USB, making them a practical choice for anyone needing a steady, stable connection for daily office work or home use.
