The boxes are ideal for storing and serving snacks and salads. Perfect for parties and picnics, but also for keeping your yummy homemade cookies fresher for longer. The Lumina storage box can be used in the fridge, freezer, steam oven, microwave and dishwasher. The boxes are leakproof, airtight and aroma-tight, and they're super robust, too. A practical tab on the lid makes it easy to remove. With their bright colours and elegant design, these kitchen storage containers can be mixed and matched and will coordinate beautifully with any dinner service. Did you know that the round Cirqula microwave lid also fits perfectly on the Lumina storage boxes? Use them together to warm up any meal without splatters!
