The problem with most storage containers is that they take up valuable space in the cupboard when not in use, and that lids and bases usually need to be stored separately, making it difficult to find and match both elements. With the unique design of Nest Lock, the bases of the containers can be neatly nested together, and the lids can be conveniently stacked for efficient, space-saving storage. Since each element is also color-coded, it is very easy to match the lids to the bases when you need them. All products in the Nest Lock range can be combined with each other, allowing you to create your own collection that meets your needs, whether for refrigerator or freezer storage, cooking in small batches, or packing lunches for the family. All containers come with secure, airtight, and leak-proof lids.
