The problem with most storage containers is that they take up precious cabinet 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 Nest 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 containers feature lockable, airtight and leakproof lids and are freezer, microwave and dishwasher safe. Set Includes: 2 x 8 fl.oz 2 x 18 fl.oz 2 x 37 fl.oz 2 x 63 fl.oz 2 x 101 fl.oz 10 x lids
