Discover the ultimate technical drawing pen set designed for precision linework in architecture, engineering, graphic design, and illustration. This professional – grade set offers a wide range of tip sizes, from 0.20mm to 3.00mm, along with a specialized brush tip, catering to all your artistic and technical needs.
The pen bodies are crafted from light beige/off – white plastic, which is smooth, durable, and lightweight. The nibs and tips are made of different materials to suit their functions. The fine – point pens feature metal nibs, ensuring consistent, smudge – free lines, perfect for technical drafting. The broad – point pens (1.00mm–3.00mm) have plastic or hard synthetic tips, while the brush tip is made of nylon or synthetic brush hair, allowing for variable line widths.
The black ink used in these pens is waterproof and quick – drying, preventing smudging on paper, vellum, or tracing paper. The set has a minimalistic design with the word “DRAWING” printed vertically or horizontally on the pen in black, and size labels in purple/black. Clear, consistent line weights are shown next to each pen to demonstrate their output, and the brush tip is accompanied by a wavy line to highlight its variable – width capability.
These pens are of standard size, approximately 15–17 cm (6–7 inches) in length, making them easy to hold. With multiple tip sizes including 0.20mm, 0.25mm, 0.30mm, 0.35mm, 0.40mm, 0.45mm, 0.50mm, 0.55mm, 1.00mm, 2.00mm, 3.00mm, and a brush tip, you can achieve various line weights. The metal nibs provide precision linework, and the brush tip offers flexibility for creating thicker lines with pressure and thinner lines with light strokes.
The construction quality is top – notch, with smooth plastic casings and crisp printing. The metal nibs are sharp and undamaged, and the brush tip is evenly trimmed. The ink flow is consistent, as evidenced by the clean, even lines next to the pens.
For technical drafting, engineers and architects can use the fine tips (0.20mm–0.55mm) for precise blueprints. Illustrators and artists can take advantage of the larger tips (1.00mm–3.00mm) and the brush tip to add bold outlines or shaded areas. It’s also great for general drawing, such as manga, comic art, or hand – lettering.
