PRODUCT MAINTENANCE AND REFILLS
Your ST Dupont writing instruments don't need much maintenance.
To restore its original shine, you can clean it with a soft cloth (never use solvent-based products).
For all silver parts, use a special silver cloth. Silver is a precious material that can show signs of oxidation.
Oxidation is a natural phenomenon that can be intensified if your writing instrument has prolonged contact with skin or rubber.
Only fountain pens require special care. If possible, use ST Dupont refills.
Don't forget to clean your fountain pen regularly.
