So the book case arrived however, 3 of the screws in the leg fell out and was stripped. So I had to remove all of them and just use is directly on the floor without the legs. I tried to use plastic wood to secure in place but it just fell off. The book case was a bit difficult to put together but  after much effort we finally secured it.  Generally, I loved the style but the leg of it were not good and the coating on the legs also was stripped. I decided to keep it because it would be too much trouble to send it back and it is functional without all 4 legs. I need someone to call me back to resolve this issue!
