STAEDTLER Lumocolor 313S Permanent Markers 4-Set

Universal Superfine 0.4 mm Waterproof Detail Markers

The STAEDTLER Lumocolor 313S Permanent Marker 4-Piece Assorted Set combines microscopic precision with industrial-grade permanence. Featuring an ultra-durable 0.4 mm superfine tip, these markers provide crisp, smudge-proof lines on virtually all non-porous and porous surfaces—including overhead projection transparency film, glass, CDs/DVDs, acrylic, metal, vellum, and slick planner pages. STAEDTLER’s innovative DRY SAFE ink technology ensures pens can be left uncapped for days without drying out. The fast-drying, low-odor alcohol-based ink sets in seconds to prevent smearing, while built-in airplane-safe technology automatically balances atmospheric pressure to stop leaks in flight. Packaged in a convenient stand-up case with four essential shades (Black, Red, Blue, Green), this German-engineered set is ideal for technical drafting, laboratory labeling, calendar planning, and detailed art projects.
