Características

• Dual-mode functionality: drafting & scoring: simply fill the adjustable nib with ink, acrylic paint, or masking fluid to draw crisp, sharp lines on paper and parchment. need to mark leather, cardstock, or soft metals? just switch to the hardened steel scoring tip to create clean, precise, and permanent marks.
• This dot-and-dash drafting pen set comes equipped with multiple brass wheels, each capable of rendering a unique line style—including continuous dotted lines, various dashed patterns, combined dot-and-dash sequences, and decorative borders. swapping out the wheels takes mere seconds, instantly transforming the pattern produced by this vintage-style drafting instrument.
• Collector-grade drafting instrument: the spring-loaded arm emits a crisp, rhythmic "click" during operation—a soothing cadence that helps the user maintain focus. whether used for restoring vintage blueprints, teaching the fundamentals of drafting, or presented as a gift to architects, engineers, or illustrators, this drafting tool is an exceptional choice.
• Built to last:the pen body is meticulously crafted from solid alloy, featuring a hand-hammered texture finish. this design imparts a reassuringly substantial weight to the tool while simultaneously providing a naturally non-slip grip. its antiqued, distressed finish is designed to stand the test of time; as the years pass, it will retain its original appearance without succumbing to oxidation or discoloration.
• Precise dynamic synchronization: simply guide this mechanical drafting pen along any straightedge, and its built-in wheel mechanism ensures the body remains perfectly parallel to the ruler's edge; simultaneously, the movement of the nib is synchronized with the motion of the pen body. the result is mathematically precise, evenly spaced lines every single time—say goodbye to shaky hands and guesswork.
