We sorted out our spice collection last year. I love this! They're so easy to see and it keeps them out of the precious counter or shelf space. The jars are from Storage Box in Wellington and have magnets on the back. The metal rectangles are from Bunnings and we used our label maker for the labels.
We also installed a soft close on the doors so they wouldn't slam the spices off the doors. Our kitchen is pretty pitiful but we'll be keeping this when we replace it hopefully later this year.
