Beautiful for decor, not great for anything with heft.

They are easy to install and exactly as pictured. I find them to be lovely and uniform, and they can't with proper instructions and even extra pieces. I took away a star because they are described as "heavy duty" use, but the dowels used to mount the shelves are flimsy. Mine are mounted on combo of studs and drywall, the plates are secure and not going anywhere. The problem is the dowels themselves that fit into the corresponding holes of the shelf: they bend easily. I put three books and bookends on one shelf and watched it tip down. I did attach the bottom screws into the dowels I secure the shelf to the mounting brackets, but that's not going to save any items from sliding off as it bends down over time. I pulled the books immediately and decided to use these for decor only rather than any practical use. The stock photo suggesting lining these shelves with glass jars filled with flour, rice, and lentils is a terrible idea.

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.
