These storage boxes are really useful. They fold flat once you've finished using them so take up less room in your bag. They also fold flat in your cupboard with the lid on top so take up less room and you always know where the lovely colour coded lid is. Easy to clean and quick to dry. This is my second set.

I couldn't get on with these containers.. found they squashed down easily if not completely full. However I gave them to my sister & she's thrilled with them - no problems there. Must have just been me!! They are a great quality & fold down well for storage.

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...

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.

great storage boxes I have a larger set as well so have a box the right size for all my needs brought them as they were leak proof and they are, as filled them with water tipped upside down gave them a shake and no water came out very impressed so glad I brought them well worth the money. Daughter uses them for school so the things she makes don't leak into her school bag. have not used in dishwasher or microwave as want to keep them in great condition.

I bought these because I like the idea of having food storage which doesn’t take loads of room in the cupboard. Sadly they are a great space saver but useless at holding food. The pot collapses spilling the contents out the hole in the top unless left untouched in the fridge. The video they show where the pot is held upside down full of liquid is completely untrue, two of mine arrived with small hairline cracks in the seal meaning liquid leaks out even when the pot is fully inflated. Sadly I only realised this fault after it was too late to return the item as I would have done this if possible.

High quality and very functional storage. They are quite pricey but are far better than the normal plastic containers. Highly recommended.ProsHigh quality boxes that are very robust and feel like they will last a life-time.Easy to fit lids.Collapsible.Do not stain.Dishwasher and microwave safe.ConsPack may not have the required sizes.

Great concept and a good range of sizes and colours, the only quibble I have is that I'm not sure how airtight it is because I can hear air wheezing in and out when I apply pressure
