Nice display shelves
Color: Black
These shelves are really easy to install unless you just don’t have any kind of skill at all with putting it where you want it and making sure it’s level and marking you anchor points. Shelves themselves look good and are really sturdy for small display items. Not much work at all to put together.

Not squared shelves
Color: Rustic Wood
I thought these shelves would be squared but they are actually rounded at the corner making them a but awkward to hang especially if your walls aren't perfectly squared. They look pretty once hung but they are quite hard to hang if you go by the instructions. I would not buy these again.
