Color metal Size 350 ml & 550 ml & 850 ml About this project Durable structure. These food containers are made of 304 stainless steel and will provide long-term strength and years of use. The sturdy material is almost unbreakable, and unlike using disposables or plastic bags, you can use it widely. Environmentally friendly, reusable container. Save money and the environment by using chemical-free containers. Steel containers and BPA-free plastic lids can preserve food while ensuring a safe eating experience-it will not absorb peculiar smells or retain flavors, and can be reused and recycled to reduce waste. Keep it fresh. These containers are perfect for holding leftovers, baked goods, fruits, vegetables and snacks, and keep your food fresh for a long time. The snap-on lid provides an air-tight, leak-proof seal to maintain freshness and prevent food spills. Easy to use. Stainless steel containers are very suitable for keeping food in refrigerators or freezers. If you want to heat food, just remove the lid and put it in a toaster or traditional oven to heat it easily. For more convenience, the container set can also be washed in a dishwasher. Simply place items on the top shelf for easy cleaning when needed. Space-saving design. The set includes three containers of different sizes (350ml, 550ml, 850ml), which can be easily nested with each other to reduce the space in the kitchen cabinet when not in use. They are perfect for storing meals, sandwiches, salads, and snacks to take to work or school.
