A technical pen is a precise drawing tool used for detailed and accurate work. It has a thin, often replaceable tip that provides consistent ink flow for detailed lines. The pen typically uses ink refills or refillable ink containers and is preferred by architects, engineers, and artists for its reliability in producing clean, sharp lines. Technical pens are used for tasks requiring accuracy, such as drafting, designing, and detailed artwork.
