Great!
Color: 2-Pack White, Color: 2-Pack White
I wish I’d have taken a before photo. But imagine a bunch of spices, on a little spice shelf that makes a U formation and a bunch of spices in the middle. So many spices. So much maneuvering to find the right one.
This- this is great! Organized, easy to see, reach. Neat. Excellent investment. It doesn’t even look like I have a lot in there, but I have 46 spices in there! And you’ll notice my cabinet has a lip. Easily fixed with a small piece of wood to raise the item.

Well thought out and easy to install
Color: 2-Pack Black, Color: 2-Pack Black
Definitely organizes and maximizes cabinet space for spice storage. It’s a little rickety. If you are using glass spice jars you will likely need to use the included screws into the cabinet because the double face tape it comes with might not hold up. It might work with the plastic spice containers, but even then it seems like it would not be sturdy enough to hold the weight. The instructions were clear and it installed quickly. If it lasts, it was definitely a value upgrade in my cabinet.

Don't buy the other brands
Color: 2-Pack Black
I'd give these a 10 if I could. I bought another version but returned ii because I didn't think it was very sturdy. These were only $8 more and what a difference. They are a very well made and a lot more sturdy. The extra $8 was a real bargain and well worth it.
