Did its job for moderate weight items.
Size: 40 Inch, Color: Black, Number of Items: 1
Easy install, a little expensive for its construction. Nice appearance however, flexes under moderate weight not for heavy items.

Great addition!
Size: 40 Inch, Color: Rustic Brown, Number of Items: 1
Floating shelf was super easy to install and is a great addition above my window in my office. I used it to put some display pieces my wife wouldn’t allow me to put over our mantle. Very sturdy and looks great!

Looks Good-Not at all sturdy
Size: 40 Inch, Color: Rustic Brown, Number of Items: 1
Looks good. Not sturdy at all if you want to put any weight on it. It’s purely decorative and is not a functional shelf. I had to use toggle bolts for a hollow wall install. The hardware included was not helpful.
