When many people use microwave ovens to heat, they worry that the high temperature will deform the lid of the box and even release harmful substances. However, if the lid is removed and heated, the food will lack moisture and become stiff. The designer deeply studied the psychology of users and launched the first "breathing fresh-keeping box".

The designer added a "breathing" air valve to the lid of the fresh-keeping box. Before putting it into the microwave oven, the lid does not need to be removed, but only needs to open the air valve to keep the fresh-keeping box in a sealed, fresh-keeping and breathable state. Four-sided safety locks are designed for the fresh-keeping box to ensure the freshness and safety of the 100%.
