Ink type defines the writing experience
Three main pen types differ by ink. Ballpoints use thick, oil-based ink — economical, long-lasting and smudge-resistant. Gel pens use water-based gel ink for a smooth, dark and vivid line. Liquid-ink rollerballs come closest to a fountain-pen feel with fluid, wet writing.
In short: ballpoint for durability and economy, gel for comfort and looks, rollerball for a fluid, premium feel.
Tip size and ink flow
Tip size (e.g. 0.5 mm, 0.7 mm, 1.0 mm) affects both line width and flow. Fine tips (0.38-0.5 mm) suit small writing and detail; medium (0.7 mm) is balanced for daily use; broad (1.0 mm) is ideal for signatures and highlighting. Left-handed writers can reduce smudging with faster-drying gel or ballpoint tips.
Choosing by use case
Which pen for which task:
- Long note-taking and study: fatigue-free medium-tip gel or ballpoint
- Official signatures and documents: dark, permanent gel or 1.0 mm ballpoint
- Planners, sketching, colour notes: multi-colour gel pen sets
- For fans of wet, fluid writing: liquid-ink rollerball
The technologies behind WRITECH
WRITECH focuses on writing comfort in gel and rollerball pens. On twist-mechanism models the tip never protrudes by accident, cutting smudge risk in pockets and bags. A patented silent structure removes the click sound in quiet spaces, while low center-of-gravity technology delivers balanced, controlled writing.
These details make a real difference for students, office workers and professionals who write often and for long stretches.
Care and storage
Gel and rollerball pens should be stored capped/retracted and kept horizontal to prevent drying. On pens unused for a while, flow returns within the first few strokes. A quality pen stored correctly delivers consistent ink to the very end.
