For writing on surfaces that have to withstand low temperatures, the edding 8000 deep-freeze marker is recommended. This can be removed with alcohol. As the containers can be made of different materials and the surfaces are probably not perfectly sealed, we cannot of course guarantee that it will work 100% on all containers. The edding 142 permanent marker could also work, but this can also be removed with alcohol. Nevertheless, it is important to remember that the ink used in our markers is not food-safe and should therefore not come into direct contact with food.
