Fineliner pen SMARTMAX SmartMax Fineliner cool grey 0,1 mm — technical drawing and writing pen

SMARTMAX SmartMax Fineliner cool grey 0,1 mm is a precision writing and drawing instrument designed for fine-line work. The 0.1 mm tip delivers consistently thin strokes for technical drawing, detailed sketching and precise handwriting. Cool grey, water-resistant ink ensures clear, even lines without excessive bleeding, making this fineliner suitable for annotations, planners, diagrams and illustration accents where controlled, delicate lines are required.

Advantages

The ultra-fine 0.1 mm tip provides high accuracy for intricate details and tight line work. Smooth ink flow and water-resistant formula reduce feathering and maintain line integrity on most papers. The neutral cool grey colour offers a subtle alternative to black, useful for layering, shading and non-dominant annotations. A balanced barrel shape supports comfortable grip and steady control during extended use.

How to use

Use the fineliner on smooth paper for best results; test on a scrap sheet if using unusual or highly absorbent stock. Hold the pen at a comfortable angle and apply gentle, even pressure to produce consistent lines—excessive force may widen the stroke or damage the tip. For layered work, allow ink to dry between passes to avoid smudging. Cap the pen after use to prevent drying.

Usage recommendations

For technical drawing, pair the 0.1 mm fineliner with larger-width pens for hierarchy in plans and diagrams. When creating illustrations or notebooks with mixed media, test compatibility of the cool grey ink with markers or washes to ensure desired blending and to prevent unwanted bleeding.
