Glossary
Mild, springy line variation without full flex commitment.
Semi-flex describes nibs that widen their line noticeably under moderate pressure — more than a spring, less than a wet noodle. Plenty for expressive everyday writing and signatures.
It is also the honest label for most modern "flex" marketing: enjoyable variation, not vintage drama.
