Joseph JosephThe problem with most storage containers is that they take up precious cupboard space when not in use and usually require the lids and bases to be stored separately - which make finding and pairing both elements a hassle. With the unique design of Nestâ„¢ Lock, container bases nest neatly inside each other and lids clip conveniently together for efficient, space-saving storage. As each element is color-coded too, it's very easy to match lids with bases when you need them. All products in the Nestâ„¢ Lock range work together so you can build your own collection to suit your needs, whether it be for fridge/freezer storage, batch cooking or family lunch boxes. All containers feature lockable, airtight and leakproof lids.841979705028420000337
