Review: Fabulous! - 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... Review: Lovely boxes - 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. ## Features - ✅ FULLY COLLAPSIBLE, STACKABLE & COLOUR-CODED >>> Say goodbye to that nightmare cupboard!

And does the lid microwavable?** A: Hey C H Nguyen, lid is microwaveable. The button is actually a removable plug, the idea is to take it out when microwaving to allow steam to escape.:) **Q: Where is the place of production?** A: Don’t know, registered office is in London **Q: Hi do you have the round ones in yet as you said November and I would like them please to go with the rectangular ones I ordered for my daughter,** A: Hey Linda, thanks for reaching out to us. we don't have the Round containers back as yet. We are expecting them to arrive on Tuesday. You can check back next week.Cheers, Wowzr **Q: Hi! the containers are made of silicone (so bpa free in theory). how about the lids? can anybody see "bpa free" on them? thanks. anna** A: No I can only see the words 'Flat Stacks' - sorry ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fabulous! *by F***I on 7 November 2018* Great for sandwiches in a backpack as you can collapse them down when empty.
