Through our technicians' repeated adjustment and improvement, we have made a great leap in quality, function and practicality. In April 2020, the new type of fixed buckle hidden lunch box was patented. We adopt ergonomic design. When the buckle of the lunch box is opened, it is gently pushed and stored in the top cover of the lunch box, so that the buckle does not occupy the surface area of the lunch box, which is flexible and beautiful;

 

When you need to fasten the lunch box, you can easily pull out the buckle and fasten the lunch box.

 

The whole operation process is simple and convenient. This type of lunch box has single and double layers. According to the meal quantity of the diner, the food types can be selected flexibly. The thermal insulation silicone rubber ring makes the food keep warm for a longer time and locks the fresh taste. The unique silica gel vent plug makes the opening of the lunch box more labor-saving and makes the heat dissipation of the food faster after heating.

 

The fixed buckle can hide the lunch box, fully sealed, leak proof and heat preservation, which can meet the customized requirements of major customers for the plate type, color, pattern and logo
