How precise are the PC-3M tips for fine work?

The PC-3M uses a bullet-style tip that measures approximately 0.9–1.3 mm, giving crisp lines and controlled strokes. The tip is reversible for different stroke widths and stays springy over many uses, which helps keep detail work steady session after session.

• Fine 0.9–1.3 mm reversible bullet tip for sharp lines and small fills
