Marker BLOW 7797 for drawing lines, tip size 1–3 mm, permanent ink

BLOW 7797 marker for drawing lines features a conical tip designed to produce strokes between 1 and 3 mm. The marker uses permanent ink formulated for reliable, long-lasting marks on paper, cardboard and similar absorbent surfaces. Its tip construction supports consistent line width, making the tool suitable for precise line work, sketches, technical drawings and everyday labeling in school, office or craft settings.

Advantages

The marker delivers steady ink flow and uniform stroke width thanks to its durable conical tip. Permanent ink dries quickly and resists smudging on common porous materials, ensuring marks remain legible over time. Compact design and tip range allow for both fine and slightly broader lines without changing tools, which simplifies tasks that require variable line thickness.

Suitable for

• Technical drawings and drafting where consistent line width is needed
• Sketching and illustration with controlled strokes
• Labeling files, boxes and school supplies
• Craft projects on paper and cardboard

Key specifications

• Tip shape: conical (needle-to-bullet style) allowing 1–3 mm stroke width
• Ink type: permanent pigment-based ink for porous surfaces
• Suitable surfaces: paper, cardboard and similar absorbent materials
• Application temperature range: standard indoor use
• Form factor: handheld marker with cap

How to use

Remove the cap and test the marker on a scrap piece of the same material to confirm line width and ink behaviour. Hold the marker at a comfortable angle and apply even pressure to obtain strokes within the 1–3 mm range; lighter pressure yields finer lines, while a flatter angle produces broader strokes. Replace the cap immediately after use to prevent the tip from drying and store the marker horizontally or with the tip down for short periods to maintain ink flow.

Usage recommendations

For best results on important documents or long-lasting labels, allow the ink to dry fully before stacking or handling. Avoid non-absorbent or glossy surfaces if permanence and adhesion are required; test the marker first on any unfamiliar material.
