wall-mounted bathroom shelf organizer.

It is designed for organizing toiletries and bathroom accessories, such as shampoo, conditioner, soap, toothbrushes, and lotions. 

The shelves are often made from materials like aluminum or stainless steel, offering durability and rust resistance. 

Many models feature a hollow or slatted bottom design to allow for quick water drainage and keep items dry. 

These shelves can be installed using self-adhesive methods or by drilling, and some include features like hooks or towel bars for added functionality.
