Real good quality, very sturdy, and it came with screws and drywall anchors. I would recommend. Only thing is it came with twice the drywall anchors that I needed and missing 2 screws. Not a big deal for me, but someone without screws laying around would have to buy a whole box for 2 screws. Other then that, it’s a good product and would buy again.

Amazing quality brackets

Size: 7.25 INCH, Size: 7.25 INCH

When I received my order I was very impressed with how the brackets were packaged. Once opened up, the steel brackets are amazing quality, and comes with all the screws needed. The only downsize is the screws are lower quality so by the time I got them in they were stripping where the screw driver sits. Same with the drywall attachments. I only used two dry wall attachments per shelf because I didn’t want to ruin my walls with giant holes. It seems to hold adequate weight. I put the regular screws in the bottom holes and through the wood to secure shelf from sliding. Overall I am very pleased. I will be ordering again when I do my bathroom shelves.

Ignore the “Frequently returned item” message!

Color: Walnut Color, Color: Walnut Color

I usually don’t write reviews but I thought I should for these shelves. I was a little skeptical on these based on the “Frequently returned item” message but I decided to give them a shot and I’m glad I did! These shelves are solid and well made, beautiful color, fit perfectly in the corner of my wall, and are easy to hang. I’m not sure why they are frequently returned but I will be ordering another set for my wife’s side of the room.
