I absolutely love these floating shelves.
Color: White, Size: 15.7 inch, Color: White, Size: 15.7 inch
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.

I'm using them to decorate with small plants and some accessories, and they look very pretty. In addition, they feel firm and resistant, they do not seem to be of poor quality. I like that they come in different sizes, which allows you to play with the distribution and give a more decorative touch to the
