Detachable Case: The Slim Book case detaches from the keyboard which allows you to place your device on one surface and still type with the keyboard on another. The detachable case also lets you function in four modes: book, keyboard, case, and video. Built-in Holder for Apple Pencil: This feature stores your Apple Pencil safely when you're not using it and keeps it close by when inspiration strikes. Strength and Style: Slim Book has a sturdy overmold that absorbs impact and withstands drops up to one meter; the attractive, tear-proof fabric on the outer case has a professional look and feel. Laptop-style Keys: Low resistance and optimal key travel make typing fast and easy, and the backlight feature available in seven different colors lets you type in lowlight conditions. Multi-Device Pairing: Slim Book lets you pair with two separate devices simultaneously and toggle back and forth between them. Adjustable Cradle Hinge: Slim Book's sturdy cradle hinge holds your device securely at multiple viewing angles. Rechargeable Battery: The long-lasting battery lets you type up to two years between charges.
