These are great for my coffee bar! These shelves are easy to install and came with all the hardware needed. What a great value for your money, especially when you get 3 of these cute shelves. I love how they help organize my coffee bar area and the size fits perfectly.

If the set screws were white the shelves would be perfect.
Color: C. White - Modern Minimalist Style, Number Of Shelves: 3, Size: 15.7inches
I'd give 4 1/2 if there was one. The shelves thwmself are nice I just don't like the visible little black set screws. The shelves themself look great and are not wobbly at all if you install correctly. I purposely installed the bracket upside down because of the little black setting screws; I didnt want them showing because the shelves are above eye level and the screws are black and I didn't want them showing. But that made the shelf lean amd wobbly so I turned them back over the way they are supposed to be and that made them level and sturdy. I guess I'll paint the little screws.

Great shelves with basket storage
Size: 16inch, Color: 2 Sets, Size: 16inch, Color: 2 Sets
I was looking for shelves that had storage and these have by far exceeded my expectations. I love them! They came well packaged with everything needed to hang them up. It took us less than 5 mins to hang them. They are sturdy and stable. I definitely would recommend this product. We have them hung on the wall above our coffee bar.
