Worth it.
Color: Brown, Size: Large, Color: Brown, Size: Large
These shelves are great. They felt light in my hands but I can assure you they do hold their weight. As you can see I have lots of crystals on mine. They are easy to assemble and look nice. I recommend them.

The wood was light but when I anchored them into the wall and they were very sturdy. Looked very cute on the wall. Affordable and easy to install if you’re handy.

Great besides the finish
Color: Wooden, Size: Medium
These are great. Only thing I wish it would’ve mentioned is they aren’t finished and can give you splinters unlike other shelves. But otherwise, they work for what they needed for, looks great, and easy to assemble for the price. They seem sturdy, but I don’t have much weight on it. Just something to keep from the kiddo

Small shelves, great value
Color: Wooden, Size: Medium
These shelves were great for an area out of the way, would not be perfect for everyone. Super sturdy and easy to install however the wood seems untreated and still a bit rough. The brackets don’t blend well and seem a bit out of place but these small and light shelves have been great at holding small items. I might not trust them with anything too heavy but they have held anything I tried. Only complaint is that they are a bit on the small side as far as depth goes. Other than that, they are awesome. If the brackets looked more sleek and the wood was stained it would be perfect for anywhere.
