Applicable Size Range → Dimensions: Fits Keyboards 16.54 inches to 17.32 inches (420 to 440 mm) Wide, Vertical Fit: 8.27 to 8.66 inches (210 to 220 mm) Deep The Universal Keyboard Cap is Green Onions Supply's thinnest protector ever. This 0.025 mm thick film is 5 times thinner than the thinnest leading custom-molded keyboard covers (which are 0.12 mm thick), providing superior levels of typing sensitivity, comfort, and accuracy. This pack includes 3 Universal Keyboard Cap Protectors. Universal Keyboard Cap stays in place with simple and secure elastic bands that wrap underneath your laptop. It’s called “Universal” because it doesn’t require custom molding for each key—its ultra-thin and stretchy design allows you to type through it even when stretched flat over the keyboard. This model fits most 17 to 18 inch (measured by diagonal screen size) laptop or notebook keyboards, regardless of language, layout, or special key shapes. Its flat and stretchable structure has another benefit: no molded edges or grooves for gunk, dirt, dust, stickiness, oil, or spills to accumulate. The smooth surface also makes it easy to wipe clean. The Universal Keyboard Cap is designed for semi-disposable use. It’s far more durable than traditional disposable protectors that wear out in a week, typically lasting 3–6 months of frequent use before needing replacement. While it may not be as long-lasting as thick molded covers, it offers unmatched comfort and is cost-effective to replace. Ideal for public computer areas like libraries or computer labs, and also great for homes, offices, clinics, or dental settings where keeping the keyboard clean is important. There's no need to search for exact models or deal with layout compatibility—just check your laptop’s size and you're ready to go.
