When disasters happen, we don't have a refrigerator to keep our temperature-sensitive drugs or vials for patients. This box should be packed at optimum temperature in the lab, or factory, and LED or LCD ON the box which works with a battery, show inner box temperature. The outer box is covered with heat reflective nano insulation coat which keep the inner temperature. The outer box is anti-shock. If something happens and the inner box is damaged, the LCD shows that this product should not be used. We can use this box for any material which is temperature sensitive.
