Bought two of these because of our huge spice collection--and they are also excellent for holding olive oil, vinegar, wine bottles, boxes of coffee filters, and bags of disposable coffee cups!  They enabled me to rearrange my kitchen cabinets after I relocated lots of small things that were cluttering up my cabinets.  They are sleek and slide easily and hug each other and the wall.  Got them in gray because that color is a better match for my stainless steel kitchen appliances.  Very happy with them!
