Great shelves!
Size: 10"D x 15.7"W, Color: Black, Size: 10"D x 15.7"W, Color: Black
Perfect for what I needed. I sanded them, painted them white, then hung them above my washing machine and dryer to hold some laundry supplies. They made laundry easier! The are sturdy. It took no time to install. They’re heavy but not so heavy that they sag or drag. It came with screws and anchors that made installation a breeze. They look great! Highly recommend.

Stylish & sturdy 3 floating shelves
Size: 11.6"D x 15.7"W, Color: Black, Size: 11.6"D x 15.7"W, Color: Black
I bought these 12-inch deep floating shelves for my son’s room and they turned out great. The extra depth makes a big difference compared to standard floating shelves. He’s able to fit books, trophies, and some of his collectibles on them without everything feeling cramped. The shelves feel sturdy and well made once installed. The hardware that came with them worked well, and they sit flush against the wall which gives that nice clean floating look. They really helped add storage while also making the room look more organized and put together. I added lights underneath which I also bought here on Amazon... I also like that they’re deep enough to actually be functional, not just decorative. My son is using them every day and they’re holding up really well. Overall I’m very happy with this purchase and would definitely buy them again for another room.
