Consistent line weight defines Gothic lettering and cartoon work, Round nibs deliver exactly that. Unlike pointed nibs that respond to pressure variations, these produce uniform strokes from any angle, essential for architectural borders, poster lettering, and display work where every line needs identical weight. Steel construction maintains rigidity through extended sessions, while the rounded tip glides smoothly through curves without catching or splattering.

The sizing system runs counterintuitively: B-0 creates the broadest line, B-6 the finest. This range covers everything from bold poster headlines to delicate cartoon details, letting you scale lettering projects without switching techniques. Each nib fits standard holders (sold separately), the Speedball No. 9451 provides reliable everyday performance, while General's Cork Grip reduces hand fatigue during longer sessions.

Speedball manufactures these nibs to exacting specifications, ensuring consistent performance across replacements. The set of six includes a basic holder plus the complete B-series range, giving you immediate access to every line weight these nibs offer. Calligraphers working in foundational or Uncial hands appreciate the predictable strokes, while illustrators value the control for inking clean, professional borders.
