Made of cowhide leather with a soft suede interior, the Smartphone Experts Book Case provides a great way for you to carry your G1 in a case that opens like a book and stays shut with a Velcro flap closure.
The right side of the case holds your G1. There are cutouts for the screen, camera and the various side buttons. The case holds your G1 snugly in place. The left side is just the case's cover (that's what makes it especially slim and convenient).
It's a great looking way to conveniently carry your device.
