Joseph Joseph Nest Lock Plastic Food Storage Container Set with Lockable Airtight Leakproof Lids, 10-Piece, Multi-Color

The containers look good and fasten securely, but stacking them is a bit fiddly. I'm also grumpy because someone put one in the microwave closed and it kind of collapsed, so it's spoiled my set!

The containers are quite sturdy and I quite like the idea that, when empty, they nest together and don’t take up too much space in a cupboard. But, and it’s a big but, I find some of the lids are almost impossible to 'snap on'. There's one lip which needs to hook over another before you can snap down the lid and a great deal of force, banging on the table top, pulling and pushing is required before you can achieve this. If I hadn’t thrown away the packaging I would have returned them. An expensive mistake. I’m hoping that at least they are airtight, although some reviews say that they leak. Maybe I’ve just been unlucky with the batch I received. I should’ve stayed with Lock'n'Lock. Would not recommend.
