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