Marker ICO ICO 11 Conical 1–3 mm Black Plastic Body, permanent ink

The ICO 11 Conical marker features a conical 1–3 mm tip and a black plastic body designed for consistent permanent marking. The marker delivers a stable ink flow suitable for producing both fine lines and broader strokes, enabling clear, legible marks on a range of common surfaces. Its form factor balances control and comfort for routine tasks in office, workshop or packaging environments.

Advantages

The conical 1–3 mm tip allows precise writing as well as wider marking without changing tools. Permanent ink provides good adhesion on paper, cardboard, plastic and many non-porous surfaces. The black plastic body offers a solid, lightweight housing that resists everyday wear and supports easy handling during extended use.

How to use

Shake the marker gently before use to ensure uniform ink distribution. Remove the cap and test the tip on a scrap surface to confirm the expected line thickness. Apply moderate, even pressure to produce a controlled line; hold the marker at a steeper angle for finer lines and at a shallower angle for broader strokes. Replace the cap after use to prevent drying.

Usage recommendations

Store horizontally or tip-up to maintain consistent ink flow. Avoid prolonged exposure to direct sunlight and extreme temperatures to preserve ink performance. For best results on non-porous surfaces, allow ink to dry completely and, if necessary, test on a small area to check adhesion.
