Designed to fit the Logitech K270 Wireless Keyboards, these protective covers wrap tightly around every key and the entire keyboard to protect it against liquids, dust and more. The thin layer of silicone delivers a great typing experience for students. Schools can allow multiple students to safely use the same keyboards in computer labs, libraries and other shared spaces, knowing they can easily disinfect them after each use. The seal protects against damage from sanitizing wipes or liquid.
