IDenti-Pen features a dual point and leaves a permanent mark on most nonporous surfaces. One end is for details, with an extra fine plastic point that won't break down. The opposite end is for broader lines, with a tough fiber point built for heavy use.
This waterproof pen writes on leather, metal, wood, glass, film, plastic, photographs and more. The ink is low-odor and resistant to water. By Sakura.
