The Corner Pantry  Door Step In comes standard with crossed over shelving as seen below.  (These shelves can be specified for "L shaped " instead). 

For delivery purposes this is split into 2 parts as highlighted below. Once on site these 2 parts can be screwed together.

There is a separate angled top that is fitted to tie the top half of the cabinet together. The Step In Corner pantry also has a loose bottom that is fitted on site as well as a smaller angle piece to create the look of a double thickness bottom.
