Each dual-ended marker pairs a durable nylon fiber brush tip that springs back after heavy pressure with a precise 0.8 mm fine tip for detailed outlines and text. Filled with water-soluble, acid-free dye ink, these pens blend smoothly across bristol board and watercolor paper without bleeding through or releasing strong odors. Select individual grey values from whisper-soft N89 highlights to dense, velvety N35 charcoal tones to build monochromatic value studies, render architectural perspectives, or shade expressive modern calligraphy. The self-cleaning nibs quickly disperse foreign pigments with a few brush strokes on scrap paper, keeping your neutral gradients pure.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTwo Nibs on One Body:\u003c\/strong\u003e Flexible nylon brush tip yields hairline to 6 mm sweeping brush strokes, while the opposite bullet tip handles tight hatching.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWater-Soluble Blendable Ink:\u003c\/strong\u003e Dilute with water or a colorless blender pen to generate soft washes, ombré gradients, and subtle glazing.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResilient Nylon Fibers:\u003c\/strong\u003e Brush nib flexes under varying hand angles and returns to a pointed tip without fraying or softening.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOdorless \u0026amp; Bleed-Resistant:\u003c\/strong\u003e Formulated with non-toxic, acid-free water dye that won't strike through medium-to-heavy art papers.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDedicated Monochromatic Spectrum:\u003c\/strong\u003e Individual grey numbers allow artists to purchase exact refill shades for complex shadow hierarchies.\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 Tombow\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e ABT Dual Brush Pen\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDual Tips:\u003c\/strong\u003e Flexible nylon brush nib (1–6 mm) + Fine bullet nib (0.8 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInk Formulation:\u003c\/strong\u003e Water-based dye ink (acid-free, odorless, blendable)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAvailable Shades:\u003c\/strong\u003e N35, N45, N49, N52, N55, N60, N65, N75, N79, N89\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecommended Paper:\u003c\/strong\u003e Smooth bristol, mixed media, or hot-press watercolor paper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMade in:\u003c\/strong\u003e Japan\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eHow do the grey value numbers correspond to shade darkness?\u003c\/strong\u003e\u003cbr\u003e\nHigher numbers indicate lighter tones (e.g., N89 is very pale grey), while lower numbers produce deeper, darker values (e.g., N35 is dark charcoal).\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I use these pens for watercolor techniques?\u003c\/strong\u003e\u003cbr\u003e\nYes, touching a wet paintbrush to the applied pigment lifts and diffuses the ink into translucent watercolor-like washes.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes the ink bleed through regular sketchbooks?\u003c\/strong\u003e\u003cbr\u003e\nThe water-based formula does not bleed through heavier drawing paper (above 100 gsm), though very thin notebook paper may experience light show-through with heavy layering.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhere should I write if I need assistance with my parcel?\u003c\/strong\u003e\u003cbr\u003e\nSend your order reference directly to our support inbox at szjyf@outlook.com for prompt after-purchase support.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat is your return and cancellation policy?\u003c\/strong\u003e\u003cbr\u003e\nOrders can be canceled for a full refund at any time prior to tracking generation and carrier pickup.
