For some reason things went steadily well with the set up of this bookcase only to have something go oddly wrong at the very end.  The back of the case comes with two thin metal rods that are supposed to criss cross from its top to its bottom. I got the first two attached but the second pair could not be attached because there is a hole missing or its on the opposite side.  It doesnt make sense though because every other part was put together and is exactly as the diagram says it should be.  The case is tiny but so is my living space and its super lightweight but its still standing so yay!  I stored the extra rods in my closet.
