The LUMOCOLOR Permanent Marker is excellent at being smudge-proof and water-resistant on almost all surfaces and features an extra-wide chisel tip, ensuring you almost always have the right solution at hand. Thanks to DRY SAFE technology, the markers can remain open for days without drying out. They dry in seconds, making them ideal for left-handed users. Black and green are light- and weather-resistant, vibrant in color, low-odor, xylene-free, and refillable. The marker has a blocked tip. The shaft and cap made of PP ensure a long lifespan. Airplane safe - automatic pressure equalization prevents the pen from leaking on airplanes. The ink is free from xylene and toluene.
