Important note on our magnetic articles
Montblanc items equipped with a magnet should not be used by individuals with a pacemaker, defibrillator, implanted insulin pump, transdermal drug delivery patch, or any other electronic medical device, nor during pregnancy or breastfeeding.
It is also not recommended to use these items near machines or high-voltage cables. The magnetic field emitted by these items can damage objects sensitive to magnets such as credit cards or other magnetic cards, sensitive data storage or display devices, personal assistants, video/audio tapes, and similar items.
The magnetic field emitted by these items can also interfere with the proper functioning of mechanical and quartz watches, which is why it is preferable not to store watches near magnetic items. These items should be kept out of reach of children.

Care tips
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.
