XYPEN White Jumbo Graffiti Markers 6-Pack

Bold 15mm Opaque Coverage & 3-in-1 Line Versatility

The XYPEN White Jumbo Graffiti Marker 6-Pack is engineered for massive coverage, high-impact lettering, bold poster displays, and professional street art murals. Equipped with a heavy-duty 15 mm rectangular block felt nib, this marker features an innovative 3-in-1 multi-angle stroke design: glide along the full 15 mm wide face for rapid block-fills, tilt to the 5–6 mm edge for strong calligraphy lettering, or turn to the 2–3 mm corner for sharp outlining and accents. Formulated with high-density, water-based white acrylic pigment, every stroke dries quickly to an intensely opaque, waterproof, and UV-resistant finish across both porous and non-porous surfaces.

Frequently Asked Questions

How do I activate the 15mm jumbo marker before first use?
Keep the cap securely fastened and shake the pen thoroughly to mix the dense white pigment. Remove the cap, gently press the felt nib downward onto scrap cardboard several times until the white paint saturates the tip, and you are ready to paint.

Can these markers be used on storefront windows and car glass?
Yes. The opaque white acrylic adheres smoothly to clean glass surfaces for bold lettering and window displays, and can be removed later from non-porous glass using a scraper or glass cleaner.

Will the 15mm nib fray when used on rough surfaces like wood or stone?
The dense, compressed industrial felt nib is designed for high abrasion resistance, ensuring consistent line edges even on textured timber and stone.
