SAKURA Identi-Pen,Fine/Extra-Fine Tips,Waterproof,Low-odor,Black
0.4 mm and 1.0 mm tip size
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. Waterproof pen writes on leather, metal, wood, glass, CDs, plastic, and photographs. The ink is low-odor and resistant to water. Alcohol-based cleaners will remove ink from nonporous surfaces. IDenti-pen meets nontoxicity requirements.
