If you’re hunting for the best coloring pens for adults and you’ve already burned through a few cheap marker sets, the Tombow Dual Brush Pen set in Tropical is the kind of purchase that tends to stick around on the desk. Ten pens, nine colors, one blender, and a tip that behaves more like a brush than a felt nib.
These are water-based pens, which means you can push the ink around with a wet brush or the colorless blender long after you’ve laid it down, something alcohol markers won’t let you do. That single property changes how you color.
- Water-based pens ideal for coloring, fine art, illustrations, doodling, journaling, hand lettering and more!
- Set of 9 colors with colorless pen
- Flexible brush tip and fine tip in one marker! Brush tip works like a paintbrush to create fine, medium or bold strokes; fine tip gives consistent lines
The Tropical palette leans into warm pinks, corals, and saturated blues and greens, so it suits florals, botanicals, and lettering more than portrait work. It’s well-rated on Amazon and sits near the top of the drawing marker category, which tracks with how long these have been a studio staple.
Bottom Line
If you want markers that blend like paint and still write a clean line, this set earns its spot in the pen cup. Check the current listing for the Tombow Tropical 10-pack here.
Overview: Tombow 56189 Dual Brush Pen Art Markers, Tropical, 10-Pack
Each pen in this pack carries two working ends: a flexible nylon brush tip on one side and a 0.5mm fine tip on the other. The ink is water-based, acid-free, and odorless, which matters if you color at the kitchen table or share a room with someone sensitive to solvent fumes.
Nine of the ten pens are Tropical colors. The tenth is the N00 colorless blender, and it does real work rather than padding the count.
The barrels are slim and cylindrical, marked with the color number on the cap and body so you can find a shade without uncapping everything. Tombow rates the set for ages 6 and up, though the price point and blending behavior aim squarely at adults.
Flexible Brush Tip and Precise Fine Tip
Pressure controls everything on the brush end. A light touch gives you a hairline; press down and the nib splays into a stroke several millimeters wide, which is what makes these usable for hand lettering without switching pens mid-word.
The nib springs back to shape reliably, provided you don’t grind it into toothy paper. That’s the one habit that kills a brush pen early.
The fine tip runs consistent and unfussy. It handles outlining, small text in a journal, and filling the tight corners of a patterns coloring book where a brush would smear past the line.
Tips also self-clean, so if you accidentally dip a light color into a dark one, a few strokes on scrap paper clears it.
Water-Based Blending and Watercolor Effects
Water-based ink stays workable, and that’s the whole pitch. Lay down color, then go over it with a damp paintbrush and you get a soft wash that looks closer to watercolor than marker.
Three approaches work well in practice:
- Pen-to-pen: scribble color onto the blender tip, then paint with it for a diluted version of that shade.
- Paper blending: lay both colors down side by side, then work the seam with the blender.
- Water brush: a plain damp brush pulls pigment outward for gradients and washes.
The ink is water resistant once dry but not waterproof, so a heavy wet pass over finished work will lift color. Plan your layers before you soak anything.
Tropical Colors and the Colorless Blender
The Tropical grouping runs hot and bright: pinks and corals on one end, turquoise and deeper blues and greens on the other, with a few mid-tone warms bridging them. It reads as a vacation palette, and it covers hibiscus, water, and foliage without needing a second set.
What it doesn’t include is a proper black, gray, or brown, so outlines and shadows have to come from elsewhere.
The N00 blender is the piece most people underuse. Beyond softening edges, it lightens a color after the fact and can lift small mistakes on decent paper. Run it over a solid block and you’ll get a mottled, uneven texture that’s useful for skies and petals.
Who Are These Markers Best For?
Letterers and journalers get the most out of this set, followed by anyone coloring botanical or tropical-themed pages. The brush tip’s pressure range is what sells it for lettering, and the blending behavior suits large open shapes.
They’re a poor fit if you need precise, streak-free flat fills across big areas. Water-based ink shows stroke marks more readily than alcohol ink does, which is why many colorists keep both, and the trade-offs in alcohol markers versus gel pens for coloring books apply here too.
If you’re building a first kit, pairing these with a set of colored pencils covers the shading these can’t do on their own. Our roundup of the best coloring book markers for adults puts the category in context.
Pros and Cons
Pros
- Brush tip flexes from hairline to bold with pressure alone
- Ink stays blendable with water or the colorless pen after it dries
- Acid-free and odorless, fine for long sessions indoors
- Fine tip on the opposite end removes the need for a second pen
- Color numbers printed on cap and barrel for fast sorting
- Individual open stock refills available, so you can replace just the dead ones
Cons
- Bleeds through thin coloring book paper without a backing sheet
- Tropical set has no black, gray, or brown
- Water-based ink can streak on large flat fills
- Brush nibs fray if used on rough or textured paper
- Not waterproof, so finished work needs protection from moisture
What Customers Say
Feedback across tens of thousands of Amazon ratings clusters around the same points. Buyers consistently praise the brush tip’s responsiveness for lettering and the smooth, forgiving blending, with many describing these as the set that finally made watercolor-style effects approachable.
Color vibrancy draws repeat mentions, as does the value of getting two tips per pen.
The complaints are consistent too: bleed-through on standard coloring book stock is the most common, followed by nibs softening faster than expected when used hard. A smaller group notes that some Tropical shades look more muted on paper than on the cap.
Several reviewers who also use alcohol markers for coloring describe keeping both sets for different jobs.
Conclusion
This set earns a place among the best coloring pens for adults if your work involves lettering, botanicals, or anything you want to soften with water. The dual tips remove a real friction point, and the blender does more than its single slot in the tray suggests.
Buy marker paper or a smooth 90 lb cardstock alongside it. That one addition fixes the bleed-through complaint and protects the nibs, and it costs less than replacing a pen.

Frequently Asked Questions
Are Tombow Dual Brush Pens worth it for adult coloring?
Yes, particularly for large open shapes, lettering, and anything where you want gradients. They cost more per pen than budget sets, but the nibs are replaceable by buying open stock singles and the ink blends in ways cheaper water-based markers don’t.
What paper works best with Tombow Dual Brush Pens?
Smooth, heavyweight paper performs best: marker paper, Bristol smooth, or cardstock around 90 lb and up. Rough or textured surfaces fray the brush nibs, and thin coloring book pages will bleed through unless you slide a scrap sheet underneath.
Can Tombow Dual Brush Pens be blended with water?
Yes, a damp paintbrush pulls the ink into washes and gradients well after it has dried. Use minimal water on thinner paper, since the sheet will buckle and the pigment can lift entirely if you flood it.
Are Tombow Dual Brush Pens waterproof?
No. The ink is water resistant once dry but will reactivate and move under a wet brush, which is exactly what makes the watercolor technique possible. Seal finished pieces or keep them away from moisture.
How do Tombow Dual Brush Pens compare with Copic markers?
Tombow uses water-based ink with a brush and fine tip, while Copic uses alcohol ink with refillable barrels and swappable nibs. Copic lays down smoother, streak-free flat color across large areas. Tombow, on the other hand, gives you water washes and softer edges. Our Copic Sketch 24-color markers review covers that side in detail.
