How should Birkenstock Care Essentials be stored?

Products should be kept frost-free and out of direct sunlight. It's best to avoid storing them permanently under 10°C (50°F) or above 25°C (77°F). The natural oils in our Comforting Dry Oil can crystallize in colder temperatures. If this happens, simply keep the product at room temperature and it will return to its clear state with absolutely no effect on the oil itself.
