These stackable containers are ideal for preparing, storing, and transporting your baby's meals. You can place them in the diaper bag without worrying about leaks: they are airtight and durable! Made from high-quality polypropylene, they are suitable for refrigerator and freezer use. These very practical containers can be defrosted and reheated (without the lid) in the microwave, babycook, or in a bain-marie (like the bib-expresso). These storage containers can be stacked or linked together. The stackable containers are available in three sizes: 90 ml, 150 ml, and 250 ml.
