Amazing little shelves
Color: G. Black Board & Gold Brackets, Number Of Shelves: 4, Size: 16-inch, Color: G. Black Board & Gold Brackets, Number Of Shelves: 4, Size: 16-inch
I love them! I use them in my nail room for clients and to hold my product. They are sturdy enough to put phones, keys, and their water bottles on. Being able to hang them in different ways is awesome for different aesthetics.4 different sizes. Easy to put together it came away with all the hardware you need. My only complaint is that the wood fills rough so not really able to dust them. I have to fix that

Awesome little shelves!
Color: A. Black Board & Black Brackets, Number Of Shelves: 4, Size: 16-inch, Color: A. Black Board & Black Brackets, Number Of Shelves: 4, Size: 16-inch
These shelves are actually pretty neat. Super easy to install with provided hardware and measurement paper. It's the perfect size for For smaller collections and even some frames if you wanted. I enjoyed the different styles to choose from when it comes to personal preference. Comes in three sizes for all your decor needs. Wasn't as thin as I thought it would be, now the feel isn't the greatest, but the look is pretty sweet. Held up just fine and the placement for the brackets are pretty cool. Either floating, bracket facing up or down. ideal for anyone who wants a nice looking shelf without breaking the wallet.

They hang easy!
Color: C. Rustic Brown Board & Black Brackets, Number Of Shelves: 4, Size: 23-inch, Color: C. Rustic Brown Board & Black Brackets, Number Of Shelves: 4, Size: 23-inch
I got my shelves well packaged. No defects. I did find it odd that the photos show a third way of hanging them where the brackets are hidden, but it's the only two top shown in the product photo of the hanging options that are shown on the instructions. It's easy enough anyway to hang without any instructions and I chose the second one shown anyway. They're good quality and look nice on my wall. Color is accurate and holds all my stuff the way I'd hoped/imagined. I wanted shelves that didn't stick out too far from the wall and they're a great fit. Super sturdy!

Great product!

The feeling of the shelf itself is a little off but it was super easy to put together and looks great! It comes with a mounting guide but I didn’t need it. I didn’t use to wall anchors and just screwed them into the wall and they haven’t been a problem at all!

Avoid the GOLD brackets. The finish is NOT accurate.
Color: G. Black Board & Gold Brackets, Number Of Shelves: 4, Size: 16-inch, Color: G. Black Board & Gold Brackets, Number Of Shelves: 4, Size: 16-inch
I bought the BLACK/GOLD shelves because the ones in the photo seemed to match the drawer pull knobs I bought (shown in photo below). The product arrived neatly packed in a 17x6x4in. box. I can only assume the shelves themselves are great, but I only made it as far as inspecting the metal brackets sitting at the top, they feel heavy duty, which is great, but the product's photo posted in Amazon shows a nice gold finish, and these brackets have a dark mustard paint finish (with a couple blueish speckles sprinkled into it), there's nothing gold/metallic about it. The paint color reminded me of long-gone diaper-changing days. These are getting returned asap.
