Ink and writing effect
Water-based colouring ink. Paper illustration, colouring, lettering and notebook decoration.
Duo-tip pens combine a fine point for contours with a brush tip for broader colour strokes. Water-based ink suits paper illustration and lettering, and colour-coded caps help users find the next shade in an assortment.

Duo-tip pens are the workhorse of paper illustration: one body, two working ends, zero time lost switching tools. The fine point handles outlines and small lettering, while the brush tip delivers the varying line widths that make hand-lettering and coloring look deliberate. This page gives the catalog configuration, the differences that matter between assortments, and what to verify before a bulk order.
| Parameter | Catalog Value | Custom Options |
|---|---|---|
| Fine tip | 0.4 mm, water-based ink | 0.3 mm technical point for detail work |
| Brush tip | Flexible fiber brush, medium spring | Soft brush for blending, firmer brush for control |
| Ink system | Water-based dye ink, 24-color range | Pigment ink for lightfastness, custom color sets |
| Barrel | Dual-ended black barrel, color-coded caps | White or colored barrels, custom logo print |
| Packaging | Singles, 12-color set, 24-color set | Window box, tin set, blister card, classroom packs |
Tip consistency is the failure point of cheap duo-tip sets. Ask for a 20-meter continuous line test on the fine end and a pressure-variation test on the brush end from the batch sample. Confirm the ink dry time on the paper you intend to sell: coated paper behaves differently than uncoated. If you plan a 24-color set, request the color card and check for duplicates and near-duplicates between shades; that is the most common assortment complaint.
MOQ for the catalog set configurations starts at 3,000 pens per SKU per color. Custom color sets and logo printing are quoted separately, and set packaging usually carries its own carton minimum.
