I bought this as part of an office remodel.  Held onto it until the rest of my items arrived.  In the middle if the decorating my husband opened the box so we could decide where the shelves would look the best.  I was Hortified! I thought he was kidding.  The metal part in the pictures is 100% CGI    These were not shiny plastic (which the description never disclosed that they are plastic at all) but instead opaque grey plastic like you would find in a child's tool set.   It was the worst scam I have ever purchased.   DO NOT BUY THIS PRODUCT! It won't let me upload with zero or 1 star! 
Shame on this company.
