We perfected every design detail. The topcase is of the same soft-finish grey as your Surface, making them a perfect match, and the finishing touch to a well thought-out desk space. The key travel and spacing are perfectly engineered for fast, quiet, and responsive typing. Meticulously crafted. Just like your Surface. Enjoy the solid feel of the keyboard under your fingers as you work. And it pairs seamlessly with your Surface with Wireless Bluetooth - at a range of up to 50 feet - and battery power to last a full year.
