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.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e15 mm 3-in-1 Versatile Nib:\u003c\/strong\u003e Switch seamlessly between 15 mm wide fills, 5–6 mm medium chisel lines, and 2–3 mm fine details by adjusting your hand angle.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDeep Carbon Black Pigmentation:\u003c\/strong\u003e Delivers jet-black, lightfast coverage with exceptional opacity on wood, canvas, cardstock, and painted walls.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Surface Crafting:\u003c\/strong\u003e Adheres permanently to poster boards, canvas, ceramics, stone, metal, plastic, and storefront display glass.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuick-Drying \u0026amp; Weather-Resistant:\u003c\/strong\u003e Water-based acrylic formulation resists smudging, moisture splashes, and UV fading once cured.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSafe \u0026amp; Low-Odor:\u003c\/strong\u003e Conforms strictly to ASTM D-4236 and EN-71 safety standards; non-toxic, odorless, and acid-free for studio and school use.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e XYPEN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e GM15B6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Size:\u003c\/strong\u003e 15 mm rectangular felt nib (3–15 mm line widths)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInk Type:\u003c\/strong\u003e High-opacity water-based acrylic paint\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Jet Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e 6 Markers per Pack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e China\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I activate the 15mm jumbo marker before using it?\u003c\/strong\u003e\u003cbr\u003e\nShake the marker vigorously with the cap securely attached.
