Meets my expectation. I ordered these to put on my living room wall. When I opened the box they were neatly wrapped and packaged. Super easy to put together and install. I love the rod bracket that mounts onto the wall making it easy to slide the rods into the holes on the back of the shelf. Very sturdy and holds my little decors and look nice on the wall.
