We have the Ikea sets of freezer containers - Pruta
It is nice to know that all the lids will (in theory) fit and having the tall, thin containers is a space saver.
However the sets contain tiny containers we never use, and they tend to go misshapen in the dishwasher and not shut any more.
Re-using takeaway containers is a bit of a non-starter as they are far too small for a family portion of something, we get very few takeaways, and they are all different sizes so the lids never fit the other containers.
I am very very tempted by the Joseph Joseph ones but they are very pricey (especially if they also warp in the dishwasher!
Any slightly less bank-breaking, or tried and tested and non-warping, ideas?
I would really prefer something we can keep using again and again (so, not bags) as I'd rather throw away less plastic than more.
