The Lumocolor Permanent Marker is excellent at being smudge-proof and water-resistant on almost all surfaces, making it ideal for nearly any situation. Thanks to the Dry Safe technology, the markers can remain uncapped for days without drying out. They dry in seconds, making them perfect for left-handed users. The black and green colors are lightfast and weatherproof, highly pigmented, low-odor, xylene-free, and refillable. The ink is vibrant and low-odor. The blocked tip, along with the barrel and cap made of PP, ensures a long lifespan. The marker is airplane safe, as the automatic pressure equalization prevents leakage during flights. The ink is free from xylene and toluene.
