Frequently Asked Questions

Q: Will these fountain pen replacement nibs fit my pen?

A: These nibs are designed as universal replacements compatible with most standard fountain pens. However, nib sizing can vary by brand and model. We strongly recommend measuring your current pen nib (approximately 6.5 × 16.2mm) and confirming whether you need an EF (0.38mm) or F (0.5mm) nib before purchasing.

Q: What is the difference between EF (0.38mm) and F (0.5mm) nibs?

A: The EF (Extra Fine) 0.38mm nib produces a very thin, precise line — great for detailed writing, fine calligraphy, and small text. The F (Fine) 0.5mm nib delivers a slightly broader, classic fine line ideal for everyday handwriting, signatures, and general note-taking.

Q: How do I install a replacement fountain pen nib?

A: Installing these nibs is straightforward — simply remove the old nib from your pen's grip section and press the new nib firmly into place until it sits securely. The solid metal interface ensures a snug fit with no tools required. Always handle nibs gently to avoid bending the tip.

Q: How many nibs come in each pack?

A: You can choose from three pack sizes: 5, 10, or 20 replacement nibs. Buying a larger pack is a great way to ensure you always have a spare on hand for school, the office, or your creative projects.
