Great shelves but be warned.
Color: Grey
These shelves are great for small items and can definitely hold up to their advertised weight if mounted in a stud. However, DO NOT use the longest screws at all. All the screws are low quality and are likely to break. The medium length ones are sufficient for everything. If your wall faces an exterior concrete wall: break off the tips on the dry wall anchors, they are too long.

These are a great corner option
Color: Rustic Wood
Was looking for something to set in some corners, and these fit the bill greatly. They are nice looking and easy to assemble and then put up. They hold a plant and some rock items nicely. A good purchase.

Would buy again and again
Color: Black, Size: 35.4 Inches
These are beautiful! I thought they’d be hard to install, but very straightforward and easy. They are quality and sturdy. I staggered the shelves and they hold a lot. Great value for the quality. I will be buying more for another room in the house.

Made my bathroom look beautiful
Color: White, Size: 15.7 Inches
The mounting and the color were excellent. I hung this in my bathroom and thought it was going to be a hard install for me. The hardware that came with this was very self explanatory. The fit was perfect and the quality was great. I would surely buy this item again in the future
