Three-piece PP food storage container set, large, medium, and small, household refrigerator storage boxes with pressure relief valve, microwave-safe (green).

① Three-Piece Layered Storage Set

[Large 18×18×9cm]、[Medium 16×16×7.5cm]、[Small 13.5×13.5×6cm] This set includes three sizes for separate storage of fresh fruits and vegetables, cooked food, and baby food/snacks. It keeps food neatly organized in the refrigerator, preventing cross-contamination and odors. When not in use, the pieces can be nested together to save cabinet space.

② Food-Grade PP Safe Material

Made from high-quality PP material, this set is lightweight, durable, and resistant to both hot and cold environments. It is suitable for refrigeration and microwave heating. The material is stable and odorless, making it safe for direct contact with cooked food and fruits and vegetables.

③ Pressure Relief Valve Ventilation Design on the Top Lid

The lid features an integrated pressure relief valve in the center. Press to open and close. During refrigeration, a slight ventilation prevents food from spoiling. Before microwave heating, open the valve to release heat and prevent the box from bulging and deforming. ④ Sealed and Leak-Proof: The lid fits snugly against the edge of the box, ensuring a tight seal. This prevents spills when soup or sauces are inverted, making it perfect for carrying your lunch out without leakage.

⑤ Versatile and Suitable for Multiple Uses: Ideal for storing groceries in the refrigerator, keeping leftovers fresh, a portable lunchbox for working professionals, portioning baby food, and storing snacks and dried goods – all in one box.

⑥ Easy to Clean and Durable: The smooth inner wall resists grease and grime; simply rinse with water. It's impact-resistant, crack-resistant, and reusable.
