Horrified by the Netflix documentary on the health impact of plastics, researched and picked these as an alternative for all our freezer storage. They have worked well being a good size to fit in the drawers, and the right size to keep frozen fruit from the summer. Our request would be to have some half the size as well to hold smaller portions.
The quality of materials and size of the Elephant lunchbox are great. However the salad box is not big enough for more than a side salad. Putting the smaller boxes inside 'bento style' is a bad idea because the salad box lid does not stay on securely and will pop off when bumped by other boxes or even just walking around. Either design the boxes better or include the strap with it instead of cheekily suggesting it as an extra. I regret spending so much on these products.
