A durable design More than an attachable keyboard, the Book Cover Keyboard protects your device from bumps and scratches with an improved cradle design. Its slim fit and fabric-like texture feel natural and compact. A pleasure to type on, it includes a detachable S Pen holder to keep your pen safe and ready to use. Do more than before Productivity doesn’t have to wait when you have a Book Cover Keyboard. The case communicates with the Galaxy Tab S4 when in use and Samsung DeX launches when you place it on the built-in POGO pin connector on the keyboard. Connect it to a mouse and monitor for an even more desktop-like experience.
