Keep nearly any keyboard free of dirt, bacteria, and liquids with the Universal Keyboard Protector! The Universal Keyboard Protector is a thin yet durable film sheet, which attaches to keyboards with adjustable elastic straps. The thin film is waterproof, so spills and microorganisms stay out of your keyboard, but it is also flexible and transparent, so you won’t lose the typing feeling of your keyboard or be unable to see the keys.
