D.Rect Cienkopis D400 4 colors — D.Rect fine-liner pen set D400, 4 color pens

D.Rect Cienkopis D400 4 colors is a compact set of four fine-liner pens designed for precise writing, sketching and technical drawing. The set combines consistently flowing pigment ink with fine tips that support detailed line work, note-taking and small illustrations. The lightweight, portable design makes it convenient for students, designers and office use when multiple colors are required in a single set.

Advantages

The D.Rect D400 fine-liners provide stable ink flow and a uniform line appearance across all four colors, reducing the need for repeated strokes. Fine tips enable accurate, narrow lines for detailed sketches and technical annotations. The set’s compact format keeps pens organized and easy to carry, while the ink’s quick-drying properties help minimise smudging on common paper types.

How to use

Remove a pen from the set and check the tip for damage before use. Use steady, even pressure for continuous fine lines and avoid pressing hard to prevent tip deformation. For best results on standard paper, allow a moment for the ink to dry before turning the page or stacking sheets. Replace caps after use to prevent drying of the tips.

Usage recommendations

For precise technical work, pair the D.Rect D400 pens with smooth, bleed-resistant paper and maintain light pressure for consistent line width. Store horizontally or capped to extend tip life and prevent ink drying.
