The pegs to put it together are plastic.  The doors do not touch. The upper backing was cut crooked so it couldn't be lined up correctly.  I was so far into it and had ripped the box that I kept going putting the flimsy piece together.  Upon moving it into place one of the boards came off because the peg holes were too deep and, being plastic, you couldn't pull them out to fix it.  
I also purchased a tall bookshelf of the same brand.  I will be sending it back.  I have put so many of these types of shelves together for myself and children that I can do it in my sleep.  I understand you get what you pay for but good grief.
