Whether you're moving into a new kitchen or re-thinking your food storage options, this 40-piece set is what you need. These are great for meal-prep, for leftovers and snacks, and for taking lunch to work. The unique Click and Close lids let you hear that the lid is securely closed and leakproof, and the twister lids screw on securely, so there's no worry about spilling. Not just for refrigerator storage, they're also perfect for pantry and freezer use, as well. The domed lids mean you can use the full capacity of the container without having the lid compress or smash the food as it's pressed onto the container. When empty, the containers are compact for easy storage, and when full they stack perfectly so they won't topple in the fridge. These handy containers are freezer safe, microwave safe with the lid removed, and dishwasher safe for simple cleaning.
