Nothing kills a quiet evening of colouring faster than a pen that skips, dries out, or bleeds through the page. Hard outlines and chalky pigment turn a relaxing hobby into a frustrating chore. The right gel pen for colouring should glide effortlessly, deposit rich opaque colour, and leave crisp edges without smearing.
I’m Mohammad — the founder and writer behind ProteinJug. Over the years I’ve combed through hundreds of product specs and real-user reviews to separate the sets that actually perform from the ones that just photograph well on Amazon.
This guide walks you through the best options for every style and budget so you can pick the gel pens for colouring that keep your pages looking clean and your creativity flowing without interruption.
How To Choose The Best Gel Pens For Colouring
Gel pens for colouring aren’t just about how many colours come in the box. The ink formulation, tip size, and grip design all determine whether you enjoy the process or fight the tool. Here are the three biggest factors to weigh before buying.
Tip Size Determines Detail Control
Most colouring books include both broad areas and tiny mandala-style sections. A 0.7mm to 0.8mm tip handles fine details without overshooting the line, while a 1.0mm tip fills large spaces faster. The best sets offer a range of point sizes within one pack, letting you switch pens as the page demands.
Ink Base and Drying Speed
Water-based gel ink is the industry standard because it delivers bright, opaque colour without the chemical smell of alcohol-based markers. However, water-based ink with high pigment loads or glitter suspensions tends to dry slower. If you colour quickly or drag your hand across finished sections, look for sets that customers consistently describe as fast-drying.
Glitter vs. Solid Colour Balance
Glitter gel pens add dimension, but heavy glitter chunks can clog the tip or leave uneven sparkle. A set with separate glitter and solid colour pens gives you flexibility — use the glitters for accents and the solids for base fills. Many premium sets now pair each glitter pen with a matching solid refill, which extends the life of your most-used shades.

In‑Depth Reviews
1. Oficrafted 160 Pack Gel Pens
The Oficrafted set is the most complete package for serious colouring enthusiasts. Eighty distinct colours — spanning pastels, neons, metallics, glitter, and classic shades — each come with a matching refill, effectively doubling the life of every pen. The 0.8mm fine tip strikes a useful balance for both intricate mandala work and medium-size area fills.
Users consistently praise the smooth, skip-free flow and the absence of leakage, even after extended use. The rubberised grip reduces hand fatigue during long colouring sessions, and the portable case keeps every pen organised with individual slots. Some customers note that pens nearing empty can occasionally drag, but the easy-to-swap refill tubes solve that in seconds.
Acid-free and non-toxic ink means the set is safe for all ages, and the included colouring sheets let you test each shade immediately. For a colourist who blends colours and wants replacement ink ready from day one, this is the most future-proof choice on the market.
Why it’s great
- Every colour has its own refill — rare at this price tier
- Very smooth ink flow with no smearing reported by most users
- Comfortable rubber grip prevents hand cramping
Good to know
- Occasional drag when a pen is nearly empty
- Case is sturdy but not as compact as a zippered pouch
2. Aen Art 100 Color Glitter Gel Pen Set
A hundred colours without a single duplicate. That is the headline for the Aen Art set, and for colourists who need maximum shade variety — especially in the pink, purple, and blue families — this is a standout. The 0.8mm to 1.0mm ballpoint tips handle both line work and block colour, and the 30% extra ink per pen means fewer replacements over time.
The soft, contoured grip gets positive feedback from users who spend an hour or more colouring in one sitting. The included zippered case is a genuine travel advantage: pens stay locked in individual elastic loops, and the case protects the tips during transport. A few customers report an occasional scratchy pen, but the overwhelming majority describe the flow as smooth and the colours as rich without being overpoweringly glittery.
Bonus swatch cards and five practice colouring sheets are a nice touch for testing blends before committing to a page. If your priority is a massive palette with a portable home, this set delivers the most colours for the money.
Why it’s great
- 100 genuinely unique shades with no duplicates
- Zippered travel case keeps pens secure and organised
- 30% more ink per pen extends usable life
Good to know
- One or two pens in a batch can feel scratchy
- No refills included — replace the whole pen when empty
3. U Brands Metallic Gel Pens, Set of 30
The U Brands set breaks the colouring mould by bundling four finish types in one box: 12 glitter (1.0mm), 9 pastel (1.0mm), 6 neon (0.8mm), and 3 classic (0.7mm). This variety lets you switch between a soft pastel wash and a bold glitter accent without reaching for a different brand. The thicker 1.0mm glitter and pastel tips lay down generous colour fast, while the finer 0.7mm classic tips handle outlines and small details.
Water-based non-toxic ink keeps the set safe for younger artists, and the reusable acrylic case is a thoughtful upgrade from flimsy cardboard boxes. Customer reviews highlight the consistent, jam-free glitter flow — a common pain point with budget glitter pens. The tradeoff is drying time: the thicker ink on some pens takes a few extra seconds to set, so you will want to avoid dragging your hand across fresh work.
For colourists who enjoy mixing metallic shine, pastel softness, and neon pop in a single session, this is the most versatile mid-range option available.
Why it’s great
- Four distinct finish types in one affordable set
- Glitter pens flow without jamming or clogging
- Sturdy acrylic case doubles as a display stand
Good to know
- Thicker ink takes longer to dry — smudges possible
- Only 3 classic colours for fine line work
4. LET’S RESIN Glitter Gel Pens, 18-Pack
If you hate rummaging for lost caps, the retractable mechanism on the LET’S RESIN pack is a simple quality-of-life win. Click the button and a 0.9mm fine point extends instantly, delivering a heavy sparkle effect that users describe as richer and more vibrant than most budget glitter pens. The contoured grip makes the barrel comfortable to hold, and the water-based non-toxic ink keeps the set odour-free.
Customer feedback is glowing on colour saturation and the smoothness of the initial flow, though multiple users warn that the ink is slow to dry. Smudging is a real issue if you are not careful about hand placement. A few also note inconsistent ink levels between pens — some run out noticeably faster than others. The lack of a storage case is another common complaint; the pens are slightly too large for standard gel pen cases but too small for marker organisers.
For colouring pages with broad, open areas where you want maximum shimmer and don’t mind waiting for the ink to set, these deliver the most dramatic glitter effect in the lineup.
Why it’s great
- Retractable design means no lost caps
- Glitter effect is noticeably richer than budget competitors
- Contoured grip is comfortable for longer sessions
Good to know
- Ink dries slowly — expect smudges on fast work
- No case included and pens don’t fit standard organisers
5. HUJUGAKO 48 Pack Neon Gel Pens
The HUJUGAKO pack is the leanest option here, but for a very specific user: anyone who loves neon and wants to keep costs low. Twenty-four neon colours come with 24 matching refills, so you are effectively getting 48 writing tips for the price of a single coffee run. The 0.9mm medium tip is a good fit for colouring book pages with moderate detail, laying down smooth, quick-drying ink that customers confirm dries faster than most glitter-heavy alternatives.
The set is non-toxic and acid-free, and it ships in a clear pouch rather than a hard case — fine for home storage but less ideal for travel. A few buyers note that the actual colours skew heavily toward browns and pinks, missing some bright blues and oranges shown in the marketing images. That said, the writing experience itself gets strong marks: no leaks, no dry pens out of the box, and the refill system works reliably once you get the hang of swapping tubes.
For a budget entry-level set that still offers refillability and reliable performance, this is the most economical way to start exploring gel pen colouring without a big upfront investment.
Why it’s great
- Very affordable for 24 pens plus 24 refills
- Ink dries quickly — less smudging than glitter pens
- Non-toxic and acid-free for safe use
Good to know
- Colour range is heavy on browns, light on bright blue/orange
- No hard case included — just a clear pouch
