The 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. All this is solved though with the unique stacking design of Nest™ Lock as the container bases nest neatly inside each other and the lids clip conveniently together. As each element is colour-coded too, it's very easy to match lids with bases when you need them. These multi-size sets are ideal for storing a variety of leftover food in the fridge or freezer, without the risk of leaks. All Nest™ Lock containers feature lockable, airtight and leakproof lids and are dishwasher, microwave & freezer safe, as well as being BPA free. All containers and lids also nest together, regardless of size, so you can mix and match to build a collection that perfectly suits your needs. Size: 16.9cm Height x 24.5cm Width x 20cm Diameter (stacked). Material: Plastic. 5 Storage Boxes in the set.
