The Lumocolor Special is suitable for many special applications such as coated surfaces, nano coatings, optical glass, and laboratory glass. It adheres to various special surfaces where other fine markers may not stick and dries in seconds, making it ideal for left-handers. It offers excellent smudge and water resistance on almost all surfaces. The ink is color-intensive and low-odour, and it is free from xylene and toluene. Additionally, it is extremely lightfast and airplane safe, with automatic pressure compensation that prevents the pen from leaking during flights. The PP barrel and cap ensure a long lifespan.
