Sakura Identi-Pen - Black

The Identi Pen is a dual point multipurpose marker that makes a permanent mark on most non-porous 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 fibre point built for heavy use.
The ink is resistant to water. Low odour and meets non-toxic. Alcohol based cleaners will remove ink from non-porous surfaces. Waterproof ink writes on: Peel off's, leather, metal, wood, glass, CDs, plastic, and photographs
