Too expensive but I love it anyway
Color: 1. Carbonized Black
Way too expensive for the quality of the "wood" but I love the way it looks and it holds all my plants 🪴
Holds securely against the wall when installed properly.

Beautiful, spacious yet compact, sturdy shelf
Color: 1. Carbonized Black, Color: 1. Carbonized Black
The only shelf I've ever bought and hung on a wall and I love this s**t. It is absolutely beautiful on the wall and you wouldn't think it could hold so much weight.
Installation was fairly easy with the use of a power drill and the included wall studs.
I use it to hold a few sketchbooks and journals, my PS4 games, and any other random stuff I like displaying. If I had more books I'd throw em on there no problem.

Wonderful shelf!
Wow, this is a great shelving unit and the price is wonderful. I wanted something that was modern and NOT barnboard, country feel. This is very classy and I like the metal sides and the shelves. It doesn't like cheap or flimsy! Install was easy and they provided a template too!
I am very happy and impressed with this unit!

Great low cost option!!!!
Color: Natural Wood, Color: Natural Wood
I was looking for some cute storage for my bathroom. I am a skin care product junkie. I saw lots of options but when these popped up, I thought for $19.99 I’m giving it a try. They are a really nice low cost option. They were simple to put together and hang. I’m very impressed with how much they hold and how nice they look. The hardware is very durable and the color looks great!
