High-quality stainless steel two-tiered lunch box, excellent sealing, and convenient to carry. - Brand: Seagull - Material: Stainless steel - Configuration: Two-tiered lunch box - Size: Set of 2, large and small - Features: Highly sealed design Thank you for viewing. This is a lunch box from India. I bought it because it can be heated directly over a fire in an emergency (disaster). However, it cannot be used in a microwave. I recommend it for those who enjoy outdoor hobbies. It's a set of 2. How about matching ones for couples or parents and children? The smaller one is suitable for people with small appetites. There is dirt and sticker residue in hard-to-clean areas. I've kept it in the kitchen for over 10 years, but it doesn't seem to have any rust.
