Penna fineliner Staedtler Triplus 334 R-3BK4 blu 4 pz.

The Staedtler Triplus Fineliner 334 R-3BK4 Blue 4 pcs set contains four blue fine liner pens designed for precise writing, sketching and technical drawing. Each pen features a fine metal-clad tip for controlled line work and a triangular ergonomic barrel that supports a comfortable, fatigue-reducing grip. The water-based ink delivers vivid blue color with quick-drying properties and low bleed on most papers, making these pens suitable for school, office and creative tasks.

Advantages

The pens combine a slim, metal-clad tip for consistent fine lines with an ergonomic triangular design that promotes a stable grip during extended use. Water-based ink produces clear, bright blue strokes that dry quickly and minimize smudging. The pens are lightweight and well-balanced, offering reliable ink flow for continuous writing and drawing. The set of four provides multiple spare pens for everyday use or sharing between projects.

Key specifications

• Tip type: fine metal-clad tip for precise lines

How to use

Hold the pen with the triangular barrel between thumb and forefinger to benefit from the ergonomic shape. Apply light, consistent pressure when writing or drawing to preserve the fine tip and ensure smooth ink flow. For best results, allow ink to dry briefly before stacking pages or writing over the same area. Store pens capped and horizontally or tip-up to maintain ink performance.

Recommendations

Use these fine liners on suitable paper with moderate absorbency to reduce bleed and feathering. Avoid applying heavy pressure or using on very rough surfaces to extend tip life. Replace pens when lines become faint to maintain precise, even strokes.
