About Lock & LockEstablished in 1997 in the USA, Lock & Lock specialise in airtight and leak-proof plastic storage containers. Using their four-locking mechanism, where container lids have four strong clips on each side, Lock and Lock have challenged the principal problem of existing plastic containers: imperfect sealing and difficulty in opening and closing lids.Creating a strong, airtight seal, Lock & Lock's containers keep food fresher for longer and eliminate any worry of leakage. Their storage containers are also designed to stack, saving cupboard space, while they are also microwave, dishwasher and freezer safe. Whatever you're storing, whether its leftover curry or an unfinished bag of crisps, Lock & Lock's plastic storage containers ensure it stays fresher for longer.Having gradually expanded their catalogue, Lock & Lock now sell various sizes of storage tubs, as well as specialised containers for everything from cakes and bread to cereal and juice. As they are transparent, Lock & Lock's storage containers always let you see exactly how much you have left without having to open the lid.
