Precisionstifte

Precisionstifte, also known as fine-liners or technical pens, are writing instruments designed for creating precise lines of consistent width. Unlike fountain pens, they typically use a liquid ink housed in a reservoir and dispensed through a fine metal nib. The nib's construction is crucial, often featuring a thin metal tube surrounded by a metal sleeve that draws ink from the reservoir via capillary action. This mechanism ensures a steady ink flow without the variability associated with brush tips or softer nibs.

Precisionstifte are commonly used in technical drawing, drafting, and illustration where accuracy and uniformity of line are paramount. Their ink is usually permanent and waterproof, preventing smudging and bleeding when used with markers or watercolors. They are available in a range of tip sizes, measured in millimeters (e.g., 0.1mm, 0.3mm, 0.5mm), allowing for varying degrees of detail. The ink color is typically black, but other colors are also produced. The body of a precisionstift is usually made of plastic and designed for a comfortable grip during extended use. Their refillable nature also makes them an environmentally conscious choice for frequent users.
