There are better floating shelves
Color: Rustic Brwon, Size: 16in
Doesn’t feel very sturdy like other floating shelves I’ve bought, and they slant a little. The anchors and screws that it came with all broke so we had to get our own for it to feel more secure on the wall, but still feels wobbly. Overall, it looks good on the wall after the fact, but won’t be adding too much weight on it.
