Great addition to my home.
Color: Brown, Number Of Shelves: 8, Size: 16in
This 8-piece set of floating shelves from RICHER HOUSE is a fantastic way to add both style and extra storage. The design is sleek and minimalist, giving the illusion that the shelves are floating. The set comes in a variety of sizes, which is great for creating a custom arrangement. The quality is good; the boards are sturdy and the included hardware feels solid. The biggest challenge is the installation. It can be a little tricky to get them perfectly level and flush with the wall, but once they're up, they feel secure. For the value for money, you get a lot of shelves for the price, making them a great option for a budget-friendly home decor refresh.

Perfect for collectors
Color: White, Number Of Shelves: 5, Size: 16in, Color: White, Number Of Shelves: 5, Size: 16in
Perfect for displaying Pokemon and other sports card products.
Holds ETBs and booster packs.
Includes stronger knockoff anchors, though I I didn't even use them since the stuff I placed on top is light weight.
Shelfs are made of MDF with a nice durable melamine finish. Keep in mind due to its width it does not have 16" OC holes.

good
Size: 23.6 Inch, Color: White
I recently added this bathroom shelf, and it’s been a great upgrade for organizing my space. It was easy to install and feels sturdy enough to hold everyday essentials like toiletries, skincare products, and small containers without any issues.
The design is simple and clean, which helps it blend in nicely with the rest of the bathroom. It doesn’t take up much space but still provides enough storage to reduce clutter around the sink or shower area.
One thing I appreciate is how practical it is for small bathrooms—everything is within reach, and it makes the space feel more organized overall. As long as it’s installed properly, it holds up well and stays secure.
The only downside is that heavier items might not be ideal depending on the material, but for regular use, it does the job perfectly.
Overall, a functional and affordable solution if you’re looking to add extra storage and keep your bathroom tidy.
