Perfect. Rigid, sturdy, and not a scratch on it. Box is incredibly heavy- but even after dragging it (!) inside my apartment and opening it from the wrong end, I could not find a scratch on any single piece. Really well packaged. 
Instructions are great- though it will take you awhile. It would have been nice if the instructions were a bit more explicit about siding the back parts of the cabinet- i.e. have the unfinished side of a small piece facing out. Usually I'm very careful about this but alas, mid-adventure I still ended up placing a part on backwards- and it's very difficult to go back and re-do. However, the cabinet is just what I wanted- the doors were not easy to install so that they were square, but the parts are sturdy enough that you can try and re-try without harm. Also, the cabinet is HUGE. Highly recommended.
