The Inheritance Cycle Box Set by Christopher Paolini

This is The Inheritance Cycle box set by Christopher Paolini. It includes four books: Eragon, Eldest, Brisingr, and Inheritance. One of the glued edges of the box set slipcase popped open. All books are like new except for the green one, which was closest to the edge of the case that popped open (It's a bit bent because it wasn't being held in shape).
