Joseph Joseph does it again with the 8-Piece Nest Compact Storage Container Set. This innovative, space-saving design neatly combines the bases and lids for six sizes of storage container in the same space as one. The problem with most sets of storage containers is that they take up precious cupboard space when not in use and usually require lids and bases to be stored separately. This can make pairing the corresponding elements a real hassle. With the Nest Compact Storage Container Set, bases nest neatly inside each other and lids snap conveniently together making them very easy to find. All elements are clearly color-coded for speedy pairing. When closed all containers are airtight. Lids and bases are freezer, microwave and dishwasher safe. Includes one 8-ounce, 18-ounce, 37-ounce and 63-ounce container. BPA free. By Joseph Joseph, masters of form and function.
