These open shelves have worked great for my new home that did not have drawer, wall or counter space to contain all of my spices - over 50 jars of many brands. I do have deep pantry shelves and these racks sit up against the back wall and make the spice jars easy to see and access. The few odd ones left are sitting in front of the racks. They were pre-assembled, unlike others I saw online and I had my pantry set up in minutes.
