Much smaller than expected
Color: Black, Size: 4 inch, Color: Black, Size: 4 inch
I got these to hang collectibles, but they are really small—like smaller than I expected. I almost returned them, but I needed something quick and didn’t have time. I’ll attach a picture so you can see the size. They work, just be aware they’re definitely on the smaller side.

Great Floating Shelves
Color: Black, Size: 15.7 inch
I’m really happy with the WOPITUES Floating Shelves. The cube shelf design looks modern and clean, and the black finish adds a nice touch to my bathroom decor. The shelves feel sturdy and well made, and the metal rail is a great feature—it keeps items from sliding off and makes the shelves feel more secure. I installed them over the toilet, and they’re perfect for storing toilet paper, toiletries, and small decorative items without taking up floor space. Installation was straightforward, and all the hardware I needed was included. Once mounted, the shelves stayed level and solid. Overall, these shelves are both functional and stylish. They helped organize my bathroom while also making it look more put together. I would definitely recommend the WOPITUES Floating Shelves to anyone looking for practical storage with a modern look.

I absolutely love these floating shelves. The design is modern and elegant, perfect for adding both style and organization to a bathroom or any room in the house. They feel very sturdy and well-made, and the white finish looks clean and matches any décor. The metal rails are a great touch and help keep items from falling. I use them to organize bathroom essentials like wipes, cotton pads, and toilet paper, as well as decorative pieces, and they look amazing. Installation was easy, and once mounted they feel secure and well balanced. Great quality for the price. I would definitely buy them again and highly recommend them.
