Set of 2 0.63L Rectangular Storage Boxes

Keep for food fresh for longer with this set of two Kilner storage boxes. Each 0.63-litre box is made from durable borosilicate glass with an airtight vacuum seal. A silicone valve releases steam, making them ideal for microwaving leftovers or heating snacks. The boxes can be stored in the fridge or freezer and are safe to use in the oven. Both boxes are stackable and can be popped in the dishwasher for easy cleaning.
