The Coteetci TPU Ultra Slim Keyboard Protector is an essential accessory for users of the 2021 MacBook Pro 16-inch (A2485) with M1 Pro or M1 Max chips. Engineered from premium, non-toxic TPU material, this shield provides a durable yet lightweight barrier that keeps your keyboard pristine during daily use. Its high transparency ensures that the MacBook's signature elegance is maintained and the keyboard backlight remains clearly visible. Designed for a precise fit, the protector is specially molded to cover all 78 keys—including the 12 function keys and 4 arrow keys—snugly. The ultra-slim profile (ranging from 0.13mm to 1mm depending on the specific series) minimizes typing interference, providing a direct touch feel while ensuring the cover does not slide or bounce during rapid typing sessions. Protection is at the core of this design. The waterproof and dustproof TPU material guards your chassis against everyday hazards such as coffee, beer, milk, crumbs, and powder, preventing debris from entering the internal components. The smooth surface also helps reduce the accumulation of fingerprints, keeping your workspace looking professional. Maintenance is effortless. The flexible rubber sheet is designed to resist losing its shape and can be easily removed for cleaning. If the protector becomes dirty, it can be washed with soapy water and flushed directly, returning it to a like-new condition. Because it is ultra-thin and soft, it is safe to use without risking damage to the laptop screen when the lid is closed.
