Not the quality or color combination I expected for the price, returns are not guaranteed
Color: 4 Panels Natural, Size: 4 Panels, Color: 4 Panels Natural, Size: 4 Panels
I was really looking forward to receiving this room divider as I loved the top design (unique compared to other "square" room divider tops), but sadly this was a dud. I really wanted to like this, but the finishing/quality, wood color, and rattan/bamboo coloring just did not work for me. It was packaged very well (so that earned some stars back), but for the price it did not meet expectations on quality. The wood itself is discolored in different places (beyond just "vintage" - it looked strange with random red-wood boards on the slatting on the bottom rather than truly tan wood color) and on the sides you can see it was made out of cheap plywood (with the multiple layer lines clearly showing). While I know it's supposed to be a rustic wood look, the way that pieces were joined and the direction of the grain just looked cheap and overly unfinished in my opinion. The rattan was very yellow compared to the wood and the plastic pieces - what confused me the most was that the product images show the "window crossbars" as the back of the room divider, and if that's the case, then the front shows really ugly plastic trim around the rattan. Perhaps the darker brown would have been a better choice, or ultimately a painted white one, but in general I'm really bummed the natural color one wasn't what I was hoping for. ALSO beware the seller is 3rd party, so you have to work directly with the seller to be able to return it and they will ask for photos to explain why you don't like it. If you buy, be prepared to potentially not be able to return it if the seller doesn't want to accept your return request.

Solid Floating Shelves 🛠️🏠
Color: Black, Number Of Shelves: 4, Size: 15.7in
I have installed four sets of the black floating shelves in my office. They are made of high quality materials, featuring a sophisticated black woodgrain finish with a natural texture. Supposedly, each unit can handle up to 22 pounds, though I would not recommend testing that limit with your vintage bowling ball collection if you value your flooring. They are awesome. The value is good for a set of two. Each shelf measures 22x7x1 (56x17x3 cm) inches, providing a decent amount of storage for books or decor. The installation was straightforward since the hardware for multiple wall types was included. They work well in the kitchen for spices or in the bedroom for personal belongings. One tip for a secure fit: use a level during installation and make sure the bracket is flush against the wall before sliding the shelf on, or your photos might look like they are sliding off a mountain 📐 These shelves offer a clean, modern look and stay stable once mounted correctly. They are a practical choice for adding functional display space to any room 🖼️
