Everything arrived fine, but!
I Had some issues. It says to line up the shelf and mark where the screw holes on the wall with a pencil. Problem is the hole is so small a sharpened pencil or a fine pen can’t  fit in the hole, and the thickness of the wood makes it impossible to make a mark on the wall through the hole.
Also when I went to try and screw the wall anchors in , the tip broke off immediately .
