Felt pen Staedtler 317-9 BK-1 — permanent black marker, Germany origin

Staedtler 317-9 BK-1 is a permanent black felt-tip pen produced in Germany for general-purpose marking. The pen delivers a consistent black line suitable for writing, labeling and quick marking on many common surfaces. Its design emphasizes steady ink flow and legible contrast, making it useful for everyday tasks in home, office and workshop environments.

Advantages

The pen provides a durable, water-resistant black mark that resists fading and maintains legibility over time. Its felt tip creates clear, uniform strokes with predictable ink distribution, and the single-piece construction offers straightforward handling and storage. Manufactured with attention to quality, it supports routine marking needs without complicated maintenance.

Suitable for

• Labeling cardboard, plastic and glass for storage and organization
• Quick marking on workpieces in workshops and light industrial settings
• Addressing envelopes, parcels and shipping labels
• Everyday writing tasks where a permanent black line is required

When it may not be suitable

This felt-tip pen is designed for general-purpose permanent marking, but it may not be appropriate for precision drafting or fine-art applications that require archival or pigment-based inks. It is not intended for use on highly porous materials where ink may bleed excessively, or on surfaces requiring solvent-free or acid-free certification.

Key specifications

• Ink color: black
• Tip type: felt tip
• Mark permanence: permanent, water-resistant once dry
• Origin: manufactured in Germany
• Packaging: single unit

How to use

Shake the pen gently if recommended by the manufacturer, remove the cap and test the tip on a scrap surface to confirm ink flow. Apply steady pressure to produce uniform lines; lighter pressure yields thinner strokes while firmer pressure creates bolder marks. Recap the pen after use to prevent drying. For best results on non-porous surfaces, allow the ink to dry fully before handling.

What to consider before purchase

• Intended surface: check compatibility with the materials you plan to mark (porous vs non-porous)
• Desired line thickness: felt tips produce consistent but not ultra-fine lines
• Permanence needs: ensure permanent, water-resistant ink meets your durability requirements
• Quantity: sold as a single unit, consider purchasing multiples for frequent use

Usage recommendations

Store the pen horizontally or tip-up to maintain even ink distribution and recap securely after each use. For long-term labeling on containers exposed to abrasion or liquids, allow full drying time and test adhesion on a small area first.
