Frequently Asked Questions

What is the difference between a technical pen and a regular fineliner?

Technical pens, such as the legendary KOH-I-NOOR models, have replaceable tips and refillable ink reservoirs, allowing precise work with a consistent line width. Fineliners such as Sakura Pigma Micron are disposable, contain archival ink, and are ideal for sketching, illustration, or writing without the need to maintain the pen.

How do I choose the right graphite pencil hardness?

The hardness is indicated by the letter on the pencil. Pencils marked H are hard and leave a light mark, which is useful for technical drawing. In contrast, soft pencils marked B are darker and ideal for shading or artistic drawing. For general use in the studio, we recommend choosing quality graphite pencils.

How should I care for technical pens to keep them from clogging?

Regular cleaning is essential. If you don’t use the pen for a while, the ink in the tip will dry and block the flow. We recommend regularly rinsing the tip with lukewarm water or a special cleaning solution. With KOH-I-NOOR, be sure to always cap the pen to prevent the ink inside the mechanism from drying out unnecessarily.

Are Sakura Pigma Micron fineliners suitable for watercolor painting?

Yes, artists love these fineliners because they contain water-based pigment ink. Once completely dry, the ink is water-resistant and fade-resistant. You can use them confidently for drawing outlines, then go over them with watercolors without the lines bleeding or smudging across the paper.

Which pencils are best for detailed portrait shading?

For detailed shading, you need pencils with a high graphite content, meaning soft grades from 2B to 8B. Our selection includes sets of soft pencils that let you create smooth transitions between light and shadow. Remember to use a quality eraser and paper with a fine texture, which holds graphite better and resists smudging.
