Extra‑fine permanent fabric pen in black lays down crisp lines with a 0.25 mm tip for labelling garments, signing quilts and adding durable decorative details. Ink writes on most surfaces including fabric, leather, vinyl, paper, metal, ceramic, wood, plastic and glass, and dries quickly for smudge resistance. Ideal for care‑labeling school uniforms and gear, marking tools and templates, and precision quilt signatures. Store capped and test on a fabric scrap to check bleed and permanence.
