Worst item ever
Color: White, Size: 16in
Set up shelves and not sturdy at all. Followed the instructions perfectly. Very poorly made. I don’t have the box and now I’m stuck with the item.
Garbage can here it comes.

Shelves
Color: Rustic Brwon, Size: 16in
Love the quality but got the wrong color. Company was easy to work with in return. If you need shelving these are awesome

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.

Simple, easy, and strong
Size: 16 Inch, Color: White
Kind of on the smaller side but for the price it’s just fine. Easy to install with just a screw driver if you can miss a stud, else you’ll need a drill. Strong enough to hold what a normal person would put on a shelf that size. No worries and it looks great
