Versatility might be your mightiest tool in this set of four Alvin Rapidograph® stainless steel technical pens. Coming in four different nib sizes (00, 0, 1, and 2), each pen provides the flexibility to sketch fine to broad lines with extreme precision on all types of surfaces. They come housed in a clear-faced case, and are accompanied by a bottle of universal ink for refilling, so that you will never be left with an empty, dry pen once the original supply runs out.
Alvin Rapidograph® pens are the standard for artists, designers, drafters, and engineers of all levels of expertise. This assorted case of four is the smart and economic choice to ensure that you always have a tool within reach, without having to pause mid-work stream and pour money into purchasing replacements time and time again.
