Great product
We have ordered this item many times. Easy to install and looks great. My son uses them to store/display his car model collections. We also used one to hold a sound bar in the living room.

There junk.
Color: Walnut, Size: 55"W x 12"D, 2Packs
These shelves are junk ! I had to wait 3 months to get them because they shipped by mule train which is ridiculous. The metal brackets that attach to the wall are weak. The shelves sag. They are not level front to back. Do not waist your money on these.

Great for bathrooms
Size: 24 Inch, Color: Rustic Brown
Great little bathroom shelf. I needed something smaller than a cabinet and aesthetically pleasing. It works perfect for smaller bathrooms lacking cabinet space.
