This is a convenient set consisting of a stainless steel insulated lunch box and two plastic containers, along with a storage case. I received it about three years ago. My son used it a few times, but it wasn't suitable for him as it's designed to hold a large amount of rice, so it's been sitting on the shelf. It's recommended for those who want to eat a lot of rice, as the rice container has an insulating effect. The lids can be removed for microwave use. I'm offering it to anyone who can use it. Price is negotiable. Thank you for looking.
