Just Ok.

They look nice but they aren’t sturdy and do not hold much weight. I’ve bought better ones on Amazon.

Size: 6 pcs: 15.7*5.7, Color: White
Really good wall amounts. I used the drywall anchors and it feels sturdy. I put like a 3 pound Crystal on it and it’s holding perfectly fine. I also was able to paint them with no problem would buy again.

great shelves
Color: C. White - Modern Minimalist Style, Number Of Shelves: 3, Size: 36inches
These are a a great set of floating shelves! They were easy to install, feel sturdy, and look clean and modern on the wall. The set of three is perfect for displaying decor, photos, plants or small storage items while adding extra space without taking up room. Great quality, stylish, and a simple way to upgrade any space. They work perfect for my figurines to be displayed.
