Great for sandwiches in a backpack as you can collapse them down when empty. Love the colours. Love the sturdy feel. Had one lot for a year now and they look like new and perform so well that I’ve ordered another set...

I bought these after reading the reviews, such a brilliant idea. I have only used the purple one so far but it is plenty big to fit a salad in for lunch and I love the fact it collapses after use, so no carrying bulky boxes home from work. I also love the fact they look so nice stacked in the cupboard.

These containers are perfect. They are great for all storage requirements, dishwasher, freezer and microwave proof. They also save an enormous amount of space in the kitchen cupboard

The main reason for buying these was the collapsible feature. They do fold up nicely and take up very little space in the cupboard. The whole bottom bit is made of rubber, and they tended to buckle and bounce around a bit when you try to put a lid on. Once the lid is snapped into place it it nice and secure. They keep the food fresh in the fridge, and wash up well.

After a bit of use, the orange container leaks water. I am hoping that others will not do that. Otherwise a good box set used daily for lunches and other bits and pieces. Light and an excellent space saver!

Great idea, but they don't work AT ALL. Not leak proof (therefore cannot be airtight), can't get the lids on properly, if you get the lid on and done up only three sides do up and lastly they collapse when trying to get lids on.

I am unable to make mine leakproof. Also find you cannot put a soup or liquid in them as pressing down the lid when closing the box means the box collapses and anything liquid travels all over the kitchen! Good for storage and attractive but otherwise pretty useless.

Fabulous cannot praise these enough! The dreaded box cupboard has been replaced by a neat couple of stacks. You can find exactly the size you want at a glance. I would like one or two even bigger ones if it were possible?? This is what I initially wrote but now after using them the lids do not close and one of them has even cracked. They still look good and are very convenient to stack but I wouldn't recommend them because of the lid closing issues.
