The food box contains 16 small boxes with 4 colored lids, each container measures approximately 6.5cm x 6.5cm x 4, 5cm. Each box holds up to 120ml of liquid. The containers also nest within each other for easy storage when not in use. Our storage bins are made of Bpa-free plastic, which is recyclable and environmentally friendly. Each plastic lid makes it completely airtight and securely in place for optimal food freshness and protection from harmful bacteria. A healthier alternative to Tupperware plastic. Made of certified Bpa-free polypropylene (PP) plastic, these containers are resistant to low and high temperatures so they can be heated or cooled. Great for meal prep, lunch work snacks, and storing food and leftovers. These jars can be used for a variety of purposes such as food storage, lunch boxes, pasta containers and transporting food to work, travel, picnics, storage or freezing. Reusable, microwave, freezer and dishwasher safe. Our raised lid means extra storage capacity so your food doesn't get compressed.
