Streamline your labeling projects with a professional-grade tool that never lets you down. The Staedtler Lumocolor Duo 348 eliminates the need for multiple pens by combining detail-oriented fine tips with bold marking power in a single, high-performance universal marker.
Double the Precision, Half the Clutter
Whether you are a busy educator organizing classroom supplies or a creative professional marking architectural glass, this dual-tip marker ensures your work remains crisp, permanent, and legible. The alcohol-based ink bonds permanently to nearly any surface—from CDs and glossy films to metal and stone—providing a smudge-proof finish that dries in staggering seconds.
Equipped with a ~0.6mm fine tip for tight details and a ~1.5mm bullet tip for clear visibility, allowing you to switch modes instantly without changing pens.
Engineered for reliability: this marker can be left uncapped for days without drying out (ISO 554), ensuring it is ready the moment you reach for it.
Ideal for professionals on the move; automatic pressure equalization prevents ink leakage during flights, protecting your clothes and bags.
The lightfast black ink is resistant to water and smearing, making it the perfect choice for outdoor equipment or heavy-use warehouse labeling.
Verified Technical Standards
Built with a durable polypropylene barrel, the Lumocolor Duo is designed for a long service life. Its low-odor formulation makes it a favorite for indoor environments where comfort is just as important as performance.
