The vacuum box with lid has a volume of two litres and is therefore the ideal size for storing in the cold cuts or freezer compartment. Like all plastic boxes from the FRESH & SAVE series, the vacuum fridge box is BPA-free, freezer-proof, microwave and dishwasher safe, for quick defrosting and easy cleaning. It is made of lightweight, shatter-proof plastic and the semi-transparent sides mean that it is always possible to see what you have.
