The 3165 Series pens are made of impact and chemical-resistant components for universal use with drawing and specialty inks. They feature long streamlined holders for good balance and self-polishing stainless steel points. For use on paper and drafting cloth. Each cap has a pocket clip and an air-tight double-seal liner.
Remarkably versatile, these technical pens handle like a pencil, moving in all directions without snagging or digging in to the drawing surface. The stainless steel nib, ranging in size from very fine .25mm to broad .50mm, is capable of achieving an engraver's perfection, a loose sketching style or a finely detailed pointillist technique. The kit, housed in a rigid plastic case, comes complete with one Rapidosketch pen and .75 oz. bottle of Rapidograph Ultradraw Ink for paper or film.
These technical pen sets come packed in convenient flat-shaped, hinged-lid plastic cases with a push-button release. Each set includes a 3/4 oz. bottle of black Universal drawing ink and nib keys. The 3-Pen Set includes line widths of 3x0, 0 and 1. The 4-Pen Set includes line widths of 2x0, 0, 1 and 2. The 7-Pen Set includes line widths of 3x0, 2x0, 0, 1, 2, 3 and 4.
