The ONYX BOOX Magnetic Protective Case for the Note Air3 series in Grey is a premium accessory specifically engineered to safeguard and enhance the functionality of the Note Air3 and Note Air3 C e-ink tablets. As an official companion to the 10.3-inch device, this Grey case offers a seamless integration that prioritizes both device safety and user productivity. It serves as a comprehensive solution for those looking to maintain the pristine condition of their hardware while adding versatile viewing options that expand the tablet's utility beyond a standard handheld reader. By combining a sophisticated magnetic mounting system with a professional Grey aesthetic, the case reinforces the Note Air3 C as a high-end tool for digital note-taking and color e-ink consumption.

Technically advanced and highly functional, this Grey protective cover features a robust magnetic attachment system that eliminates the need for bulky plastic frames, allowing the tablet to snap securely into place. It incorporates an intelligent auto sleep and wake function that preserves the battery life of the Kaleido 3 screen by instantly managing power states upon opening or closing the cover. A standout technical feature is the integrated magnetic flap, which not only secures the front cover but also wraps around the BOOX Pen to ensure the stylus remains attached during transit. The case is precisely engineered with dimensions of 228 by 197 by 3 millimeters and a weight of 264 grams, ensuring it remains lightweight while providing full access to the power button and USB-C charging port.

Crafted with a focus on minimalist elegance and durability, the case is constructed from high-quality synthetic organic leather in a professional Grey finish. The exterior surface is treated with a specialized anti-fingerprint coating, ensuring the Grey accessory remains free of smudges and maintains a clean appearance even after a full day of handling. Its ultra-slim profile is designed to complement the magnesium-aluminum alloy chassis of the Note Air3 series without adding unnecessary bulk. The interior is lined with soft materials to prevent scratches on the screen, while the exterior fold lines are reinforced to support the device in multiple configurations, reflecting a build quality that is both resilient and refined.

This Grey case is an essential tool for students, researchers, and creative professionals who require a versatile workspace on the go. Its unique three-way folding stand supports landscape mode for immersive reading, portrait mode for efficient document review and web browsing, and a low-angle ergonomic tilt for comfortable sketching and handwriting. Whether used in a lecture hall for taking notes, in a boardroom for reviewing reports, or in a studio for digital illustration, the Grey case adapts to the user's specific workflow. It is the ideal choice for Note Air3 C owners who need a reliable, multi-functional shield that protects their investment while traveling in a briefcase or backpack.
