Caring for your leather goods
Leather is a natural material sensitive to the effects of light, humidity, and water. To preserve the quality of your Montblanc leather item and prevent the color from fading, Montblanc recommends protecting it from prolonged exposure to high temperatures or direct sunlight. In case of contact with water, dry immediately with a soft cloth.
