Ink Recommendations
Standard dye-based fountain pen inks; avoid permanent, pigment, or iron-gall inks due to vintage internal metal parts and hard rubber.
Care Recommendations
Handle with extreme care, avoid soaking vintage ebonite in hot water to prevent discoloration (oxidation), and have the cork seal serviced by a professional vintage pen restorer.
Interesting Facts
Montblanc safety pens required the user to point the nib upward and twist the blind cap to extend the nib into writing position before filling or writing.
