The 3D Refrigerator Energy Sticker protects and improves the energy of food:

After putting the sticker on the fridge, food spoils more slowly and its vital energy is increased. This way we can ensure a healthy meal full of life energy, because the vitalised water brings energy and health into our bodies and reduces any harmful processes in the food. It also lessens the amount of certain colonies in the refrigerator including black mould, which is extremely harmful for the body.

The Sticker is put outside of the refrigerator.
