Setup, Compatibility & Care
Setup: Replacing a Montblanc LeGrand rollerball refill is straightforward. First, unscrew the barrel of your Montblanc LeGrand rollerball pen. Gently pull out the old refill. Insert the new Mystery Black refill, ensuring it is seated firmly, then screw the barrel back onto the pen.
Compatibility: These refills are specifically designed for Montblanc Rollerball/Fineliner LeGrand pens. They are engineered for models such as the Montblanc Meisterstück LeGrand series. Ensure your pen model is explicitly stated as LeGrand Rollerball or Fineliner for guaranteed compatibility. They are *not* compatible with ballpoint pens or other Montblanc writing instrument lines (e.g., Classique).
Care: Store unused refills in a cool, dry place away from direct sunlight. Avoid extreme temperatures. To clean your pen's internal mechanism when changing refills, use a soft, dry cloth.
