Not too thick and durable and sturdy.
Color: Rustic Brown, Size: 24"W x 6.7"D, 3 Pack
Just before I purchased these 3 I bought 2 sets of 2 larger ones. The color is exactly what I was needing. They are packaged together so no scratches or damage. My husband (the installer) says they are easy enough to install. They are perfect for a diy update, durable and hold plenty of weight for their size. Happy happy customer

Good quality for the price
Color: Black, Size: 30"W x 6.7"D, 3 Pack, Color: Black, Size: 30"W x 6.7"D, 3 Pack
Seamless floating shelves that look and feel great. I opted to use different drywall anchors since I didn't trust the ones that came with the product. I have bad drywall and no studs where I was mounting so that doesn't fall back onto the product. The shelves are true to size and have held up great. The shelves themselves aren't too heavy so it leaves some room to add weight onto them. I used the 30in long shelf on the left and 24in long shelf on the right to create a nice corner shelf. There are additional screws on the bottom the keep the shelves from moving off the bracket.

Beautiful for decor, not great for anything with heft.
Color: Oak, Size: 24"W x 6.7"D, 3 Pack, Color: Oak, Size: 24"W x 6.7"D, 3 Pack
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.
