The Food Preservation Box With a Lid Is Sealed With a Lid to Keep the Food Fresh. There Is a Timer On the Storage Box to Record the Storage Time. Multi-layer Food Storage Boxes Can Be Stacked Freely, Tightly and Seamlessly Connected to Prevent Food From Smelling. The Anti-sticking Texture Design At the Bottom of the Food Freezing Box Ensures That the Bottom of the Box Is Not Sticky When Refrigerated.
