Abstract: Modular storage bins provide for the bulk containment and storage of various commodities and goods, and are particularly useful in the kitchen or pantry for the storage of foods and spices. One or more identically sized open sleeves are installable beneath or alongside an existing cabinet or shelf, or alternatively may be placed atop an existing countertop or shelf. A mounting plate may be provided for additional attachment security for the sleeves, if desired. Each of the sleeves are adapted for the containment of one or more specially configured bins, with the bins being provided in various sizes. The largest bins have dimensions which are integral multiples of the smaller bins, i.e., the largest bins are two and three times the width and height of the intermediate sized and smallest bins. Thus, two half width bins, or a two by two matrix of four intermediate bins, or a three by three matrix of nine of the smallest bins may be installed in any given sleeve.
