Don't know why I never thought of getting some of these before to organized my pantry/refrigerator. My father (recently semi-retired) decided to organize theirs, and put me on to this. Bought two one-level ones and one double level - my refrigerator has never looked more organized, and I use one in a cupboard for oils and vinegars ... no more rooting around in the back for what I'm looking for. DH was convinced that this would reduce the amount of space available for storage, but as far as I'm concerned, whatever minute amount of space I'm ceding by inserting the round object into my rectangular spaces is definitely worth it. Found some lovely stainless steel ones at our neighborhood hardware store - also saw them on websites, but felt the need for instant organization (or gratification!).
