Great Floating Shelves
Color: Oak, Size: 30W x 11.6D x 2H, 2 Pack
Really pleased with the look, feel and quality of these floating shelves. Installation was easier than I imagined and the size fit my space perfectly. And best part - affordable. Would recommend and buy again.

Cute and stylish
Color: Oak, Size: 24W x 11.6D x 2H, 2 Pack, Color: Oak, Size: 24W x 11.6D x 2H, 2 Pack
The shelves look super cute in my laundry closet redesign. Not heavy duty, but that’s okay for my purposes.

Shelf is nice, bracing is garbage.
Color: Black, Size: 35.6W x 11.6D x 2H, 2 Pack
Just like all the other reviews, it sags. Regardless of how its mounted to the wall, the bracing itself is weak. Shelf is nice though, definitely would have to get different brackets to make this worth it.
