10 Stack a Boxes Food Storage Containers 1.2L 5 "The BEST storage boxes EVER!" Judith Lentelink 02 July 2012 I have been using my original sets since the 1980's! They are so durable and long-lasting, and their shape is perfect for stacking in the freezer, fridge and even the cupboard when not in use. I am buying new ones as I have given so many away over the years (8 left out of the original 20 mixed sizes) and am so glad they are still available! A brilliant product and worth every penny.
