Double-layer Frosted Lunch Box

Made of PP and PE, this lunch box with a pair of chopsticks has two independent layers, one of which has a moving clapboard built in, meeting different needs. An elastic band around the lunch box ensures it's well sealed and leakproof. It bears temperatures from -20? to 120?, suitable for refrigeration and oven heating(less than 5 mins). Remember to take down the lid and the clapboard when you heat it up in the oven
