XYPEN Black Jumbo Graffiti Markers 6-Pack

Intense Black Coverage & 15mm 3-in-1 Stroke Precision

The XYPEN Black Jumbo Graffiti Marker 6-Pack delivers high-density, deep-black pigmentation designed for large-scale poster art, bold sign writing, street murals, and striking calligraphy lettering. Fitted with an ultra-durable 15 mm rectangular block felt nib, each marker offers a versatile 3-in-1 multi-angle design: sweep the full 15 mm broad face for rapid block-fills, angle to the 5–6 mm chisel edge for bold calligraphy lettering, or turn to the 2–3 mm point for clean contour outlines. Filled with premium water-based acrylic paint, it flows smoothly without streaking and dries to an intensely opaque, waterproof, and UV-resistant matte black finish across light and dark surfaces.

Frequently Asked Questions

How do I activate the 15mm jumbo marker before using it?
Shake the marker vigorously with the cap securely attached. Remove the cap, gently press the felt nib against scrap cardboard several times until black pigment fully saturates the tip, and begin creating.

Is this black marker permanent on outdoor signage?
Yes. The cured acrylic paint is waterproof and UV-resistant. For long-term outdoor exposure on untreated wood or masonry, applying an acrylic clear coat sealer will provide additional weather protection.

Can I use this marker on smooth glass and ceramics?
Yes. It produces sharp, opaque black lettering on glass and glazed ceramics. On non-porous glass surfaces, markings can later be scraped away or cleaned off with glass cleaner if desired.
