Compatibility: Checking the size and model of our tablet before buying can effectively avoid the trouble of buying the wrong one. This case is only compatible with iPad Air (2019) and iPad Pro 10.5 inches PROTECTION: Protects our expensive tablet from accidental damage - multiple layers of protection with inner case, outer cover, built-in screen protector. In addition, we also provide a front cover without a screen protector, which can be used in cases where we already have a tempered glass film. Functionality: The kickstand is something we can't live without, we need it to prop up the tablet so we can watch or type. We also need a strap to hold the tablet securely to prevent accidental drops when using the tablet with one hand. And the pen holder is very important. Portability: We often need to carry our tablet for travel or work, so we need a shoulder strap to free our hands. Not only that, but it can be hung anywhere. For example, hang it on the back seat of a car to create a mini theater for the kids.
