The Shuttle Art 120 Unique Colors Gel Pens is one of the most popular sets for the job. For hobby colorers who want lots of variety on a budget, it’s a strong pick: every pen holds a different color, and the set spans seven ink finishes, from pastel to glitter.
- 120 UNIQUE COLORS: Shuttle Art 120 Unique Gel Pen Set contains 120 INDIVIDULE colors. Enjoy the fun of coloring! Each pen enjoys a unique color, which brings much more fun for Adult book Coloring, Scrap booking, Sketching, Doodling, Drawing, Writing, and all the other art designs.

- CUTE PACKING: It’s convenient and easy taking. What’s more, it does NOT need big space to lay when you use.
The pens lay down a 0.8 to 1.0 mm line with water-based gel ink. That width fills small spaces quickly but still gives you enough control for fine details.
Buyers often praise the vibrant colors and smooth flow. A handful of pens in some sets arrive with weak ink flow, which is the main recurring complaint.

120 Distinct Colors for Detailed Coloring
With no repeats across 120 pens, there are plenty of neighboring shades for gradients and soft transitions on intricate pages.
Several buyers who color mandalas and adult coloring books say the pens blend softly or build to deeper tones when layered. Some also note that a few colors look very close to one another, so the practical count of clearly distinct hues is a bit lower than 120.
For most coloring projects, those near-matches are still useful. Two similar blues, for instance, can give you a subtle shift for shadows or highlights within a single shape.
Seven Ink Finishes for Different Effects
Each finish has its own visual purpose, and having all seven in one set makes it easy to mix textures on the same page.
- Standard: everyday solid fills
- Pastel: soft tones that show well on darker areas
- Neon: bright accents and pop elements
- Metallic: shimmer for borders and details
- Glitter: sparkle for highlights
- Neon glitter: bright color with added sparkle
- Swirl: shifting multi-tone lines
Glitter and metallic inks sit on top of the paper and take longer to dry. Give them a moment before resting your hand on the page, or smudges can happen.
How Practical Is the Grey Case for Coloring Sessions?
For coloring at home, the grey case keeps all 120 pens organized without taking up much room on your table.
At roughly 13.6 by 6.1 inches, it fits beside a standard coloring book without crowding your workspace. The whole set weighs about 200 grams, so it’s easy to carry in a tote, too.
Snap caps protect the tips between sessions. Recap each pen firmly after use to help keep the gel from drying at the tip.

Customer Reviews
What the Overall Rating Suggests
A very high rating across tens of thousands of buyers suggests people are consistently pleased with the color quality and value. Reviewers describe the set as smooth, vibrant, and a good fit for adult coloring; several have bought it as a gift. Others use it for journaling, scrapbooking, and color-coding bills. International buyers report similar experiences.
What the Rating Cannot Tell You
Star ratings don’t show how every individual pen in your set will perform. Some buyers say a small number of pens seemed dried out or flowed poorly on arrival.
The rating also can’t tell you how the ink will behave on your particular coloring book paper. Thin pages can react quite differently from heavier stock.
Conclusion
The Shuttle Art 120-color set suits coloring hobbyists who want a wide range of shades and finishes in one affordable package. There’s enough variety for gradients, accents, and textured effects across detailed pages.
Expect a few weaker pens and some close color matches. When your set arrives, test every pen on scrap paper so you can spot any low-flow pens within the seller’s return window.

Does the 120-color set contain duplicate colors?
