Rollerball pen Staedtler 334-34 Blue, stroke width 0.3 mm, writing colour blue, 1 pc

The Staedtler triplus fineliner is a rollerball-style fineliner with a superfine metal-clad tip and a comfortable triangular polypropylene barrel. This blue writing pen delivers a precise 0.3 mm line width with water-based ink that washes out of most textiles and is designed for extended everyday use. The pen incorporates a clip for portability and an automatic pressure equalisation to prevent leakage during air travel.

Advantages

The metal-clad superfine tip provides consistent, precise lines while the triangular ergonomic barrel reduces hand fatigue during long writing or drawing sessions. DRY SAFE technology allows the pen to be left uncapped for days without drying up, and the water-based ink is easy to wash from most fabrics. The robust PP barrel ensures long service life and the pressure equalisation feature prevents leakage on aircraft.

Suitable for

• Detailed note-taking and writing
• Technical sketches and fine drawing
• Annotating documents and planners
• Colour-coding and organising notebooks

When it may not be suitable

Because the pen uses water-based ink and a superfine 0.3 mm tip, it may not be ideal for situations requiring very fast drying on glossy paper or bold, thick lines. It is also not intended for permanent marking on non-porous surfaces.

Key specifications

• Ink type: water-based
• Tip: metal-clad superfine tip
• Line width: approx. 0.3 mm
• Barrel material and shape: polypropylene, ergonomic triangular barrel
• Features: DRY SAFE (can be left uncapped for days), clip, automatic pressure equalisation for air travel
• Colour: blue

How to use

Remove the cap and write with a light, consistent pressure to preserve tip life and maintain a uniform line. Replace the cap after use to maintain optimal ink performance, although the DRY SAFE feature provides temporary protection if the pen is left uncapped. Store the pen horizontally or with the tip down for regular use.

What to consider before purchase

• Line thickness needed: 0.3 mm is suited to fine writing and detailed drawing
• Ink type preference: water-based ink washes out of most textiles but is not permanent on non-porous surfaces
• Ergonomics: triangular barrel supports extended writing comfort

Usage recommendations

For best results use on standard paper weights for note-taking and sketching; allow ink a moment to dry on coated or glossy papers. Combine with other Staedtler triplus colours for colour-coding and organising materials.
