(Pilot Custom 743 Black Sutab Pluma Estilográfica)
Among the special nibs in the Custom 743 lineup, the SU (Sutab) nib stands out for its ability to deliver smooth, precise, and fine lines. Originally developed for accurate Japanese signatures, this nib is also ideal for quick writing, clean notes, and detailed penmanship.
Unlike other fine nibs, the SU features a slightly rounded tip and a firm construction that allows it to glide smoothly across the paper without catching — even during fast writing. It’s well suited for delicate signatures and consistent, stylish strokes.
Design and Concept
The Pilot Custom 743 retains the classic elegance of the series: a glossy black resin body, gold trim, and a 14K gold size 15 nib. The SU nib is precisely polished and designed to provide a controlled, stable writing feel. Users often describe it as clean and technical — perfect for those who value confident precision in every stroke.
The name “SU” comes from the Japanese word “Sutab” (スタブ), a shortened form of “Signature Stub.” While it doesn’t have the flat tip typical of Western stubs, it was created to support quick, fluid signatures with refined control — hence the name.
Filling System
Compatible with Pilot cartridges or the included CON-70 converter, known for its large ink capacity and reliable performance — ideal for long writing sessions without interruption.
Included in the box
Includes the Pilot Custom 743 Black Sutab fountain pen, a CON-70 converter pre-installed, the official Pilot gift box, and a special surprise from Inktraveler to enhance your writing experience.
