Gel vs Ballpoint vs Rollerball: How the Inks Differ
All three roll a ball over paper; the ink is what differs. Ballpoints use thick oil-based paste that dries fast (BIC says under 2 seconds) and lasts longest. Rollerballs use thin water-based liquid ink that writes darkest but bleeds and smears. Gel ink is water-based but thickened, sitting between them; hybrids such as Jetstream thin the oil.

Notes on these facts
- Pilot G2 Premium Retractable Gel Pen (0.38 / 0.5 / 0.7 / 1.0 mm): Made by Pilot Corporation (Japan); sold in the US by Pilot Corporation of America. Made in Japan: per US retailer spec sheets (Stop & Shop, OnTimeSupplies for item 31171). Some grocery listings for a 4-pack say "Japan, USA", so origin may vary by pack. Pilot's US site doesn't state it in the sources we found. Source. Price: example listing.
- Pentel EnerGel RTX (BL77, BLN75, BLN73, BLN77, BL80): Made by ASTRUM Corporation (Tokyo), called Pentel Co., Ltd. until April 1, 2026; Pentel remains the brand. Made in Japan or Mexico: Pentel of America's 2022 product catalog gives the origin of the EnerGel RTX (BL77 metal tip and BLN73/75/77 needle tips) as 'Japan / Mexico' without saying which SKU comes from where. Retailer listings match: OfficeSupply.com lists Mexico for one RTX listing. Pentel's Japanese product page doesn't state a country. Check the package of the exact pen you buy. Source. Price: example listing. Released: Year the EnerGel line launched, per Pentel's Japanese news release of August 7, 2026. Pentel's Japanese magazine says it was sold only outside Japan at first, with Japanese sales starting in 2003. We found no separate debut date for the US RTX model.
- Pilot Precise V5 Premium Rolling Ball Pen, Extra Fine 0.5 mm (capped; item 35334 black dozen): Made by Pilot Corporation (Japan); sold in the US by Pilot Corporation of America. Made in Japan: Pilot's own promotional catalog (Pilot Pen Promo) gives Japan as the country of manufacture for both the capped Precise V5 and the V5 RT, and Stop & Shop and Hannaford list the black 2-pack as made in Japan (all read on October 20, 2026). The HD Supply listing cited earlier has been removed. Pilot Japan's own catalog doesn't sell the V5. Source. Price: example listing.

Key takeaways
- BIC says the Cristal's oil-based ink dries in under 2 seconds and writes up to 3 km from a 1.0 mm ball, which makes a line about 0.4 mm wide.
- uni says its low-viscosity Jetstream oil ink cuts writing friction by up to 50% against its conventional oil ballpoints.
- Pentel says EnerGel liquid gel has three times the lubricant of its usual gel ink and lower viscosity while writing.
- The Pilot Precise V5's 0.5 mm liquid-ink tip writes a line of about 0.3 mm, per UK retailers; Pilot gives it no dry time.
- All five example pens sit in our $ band (under $5); the G2, EnerGel RTX and Jetstream RT take refills, while the Cristal and capped V5 don't.
What’s the difference between gel, ballpoint and rollerball pens?
All three write through a tiny rolling ball; the difference is the ink: thick oil-based paste in a ballpoint, thin water-based liquid in a rollerball, and thickened water-based gel in a gel pen. The ink decides how smooth the pen feels, how dark the line is, how fast it dries and how long a refill lasts.
Pilot explains the split on its Japanese site. A ballpoint carries high-viscosity ink around the ball and lays it down as the ball turns. A liquid-ink pen draws low-viscosity ink from a tank by capillary action, through a feed like a fountain pen’s, so its line runs wider and spreads more.
A fourth type, the low-viscosity or hybrid ballpoint, thins the oil so it writes more like gel.
How do the five example pens compare?
The ballpoint dries fastest and lasts longest; the liquid-ink rollerball writes darkest but smears and bleeds most; gel sits between them. Figures are maker claims or retailer listings; see each guide for sources.
| BIC Cristal | Jetstream RT | Pilot G2 | EnerGel RTX | Precise V5 | |
|---|---|---|---|---|---|
| Type | Ballpoint | Hybrid ballpoint | Gel | Gel | Rollerball |

Viscosity is a ranking from the makers’ own comparisons and Pilot’s explanation, not measured numbers; none of these makers publishes one.
Why does gel and rollerball ink smear more?
Water-based inks soak into paper and dry slowly, while oil-based paste sits on the surface and sets almost at once. BIC says the Cristal’s ink dries in under 2 seconds; Pilot gives no dry time for the G2 or the V5, and reviewers report G2 smearing in its 0.7 and 1.0 mm sizes.
Bigger balls lay down more ink, so a 1.0 mm gel line takes longer to dry than a 0.5 mm one. Pentel says its EnerGel liquid gel dries quickly, and in a 2011 blog test the EnerGel smudged only if touched within a second or two.
Which bleeds and feathers on cheap paper?
Liquid-ink rollerballs bleed and feather most, ballpoints least, and gel pens fall in between. Liquid ink is absorbed into the paper fibres and spreads, while gel’s thicker ink isn’t absorbed as readily.
On thin copy paper, expect a V5 to show through the back of the sheet more than a Cristal. Gel’s trade-off is skipping: its higher viscosity can leave occasional gaps in a line.
Which is best for left-handed writers?
A hybrid ballpoint or a quick-drying gel pen, in a fine tip. uni recommends the Jetstream to left-handers and Pentel recommends EnerGel, both on the grounds of fast drying. Neither publishes a dry time, so these are maker claims.
Liquid-ink rollerballs are the riskiest: user reviews of the Precise V5 single out left-handed writers for smudging. Our best pens for left-handed writers roundup goes further.
How long do refills last, and what do they cost?
Ballpoints last longest because they use so little ink; gel and liquid pens run dry sooner. BIC says one Cristal writes up to 3 km, and Unsharpen notes that gel pens use far more ink for the same writing, which is why gel refills are fat.
All five example pens are in our $ band, under $5 each in multi-packs. The G2, EnerGel RTX and Jetstream RT take refills, so you keep the body; the Cristal and the capped V5 are disposable.
When did each ink type appear?
Ballpoints came first, then liquid rollerballs, gel and hybrids.
- 1938: László Bíró patents his ballpoint; BIC launches the Cristal in December 1950.
- 1963: Ohto introduces the liquid-ink rollerball; Pilot dates the V5’s design to 1984.
- 1982: Sakura patents gel ink; Pilot launches the G2 in 1997 and Pentel EnerGel follows in 2001.
- 2006: uni launches Jetstream low-viscosity oil ink in Japan in July.
Frequently asked questions
Is a gel pen a ballpoint?
Mechanically, yes: both write through a small rolling ball. Gel pens use water-based gel ink and are usually grouped with rollerballs; Pilot calls the G2 a gel ink rolling ball. Ballpoint usually means oil-based paste ink.
Which dries faster, gel or ballpoint ink?
Ballpoint ink. BIC says the Cristal's ink dries in under 2 seconds; gel and liquid inks soak into paper more slowly. Pentel's EnerGel is a gel ink marketed as quick-drying, but no maker publishes a gel dry time in seconds.
What is the difference between a rollerball and a gel pen?
A rollerball uses thin, free-flowing liquid ink fed like a fountain pen, as in the Pilot Precise V5. A gel pen uses ink thickened with gelling agents, which holds pigment for bright, opaque colours and bleeds less but can skip.
Which pen type is best for left-handed writers?
A low-viscosity oil hybrid or a quick-drying gel. uni recommends its Jetstream to left-handers and Pentel its EnerGel; liquid-ink rollerballs such as the Precise V5 are the most likely to smudge under a trailing hand.
Which pen bleeds through paper the least?
An oil-based ballpoint. Its paste sits on the paper surface, while the liquid ink of a rollerball soaks in and spreads; gel ink sits between the two because its thicker ink isn't absorbed as readily.
Which pen lasts the longest?
Ballpoints. BIC says one Cristal writes up to 3 km, and Unsharpen notes that gel and liquid-ink pens use ink much faster than ballpoints. Pilot says the G2 writes longer than the average competing gel pen but gives no distance.
What is a hybrid ink pen?
A ballpoint with thinner oil-based ink that writes more like a gel pen. uni's Jetstream, launched in Japan in July 2006, is the best known; uni says it has up to 50% lower writing friction than its conventional oil ballpoints.
