Pilot G2 Black 0.7mm Gel Pens, 12 Count
A twelve-pack of retractable black G2 gel pens with 0.7mm tungsten-carbide balls, visible ink supply, rubber grips and support for Pilot BLS-G2 refills.
Pros
- Visible ink level helps plan replacement
- BLS-G2 refill family is identified by the manufacturer
- Pilot publishes a 0.32mm written line for the 0.7mm model
Cons
- Pilot regional naming calls 0.7mm medium while the US listing says fine
- Cited G2 page does not make uni-ball style fraud-resistance claims
- Actual drying behavior varies with paper, pressure and environment
Who it’s for: Choose G2 when a long-established refill format, visible ink level and published line width are priorities. Skip it when the documented security-oriented ink properties of the 207 Plus+ drive the purchase.

A twelve-pack of retractable black 207 Plus+ medium 0.7mm pens using pigment-based Super Ink Plus+, with a seamless rubber grip and identified 70161 black refills.
Pros
- Manufacturer states water and fade resistance plus fraud resistance
- Seamless rubber grip and streamlined barrel distinguish Plus+ from standard 207
- Exact black refill number is documented
Cons
- Current page does not publish a line width for direct comparison
- Security properties do not make a document physically indestructible
- No controlled head-to-head drying result supports a faster claim here
Who it’s for: Choose 207 Plus+ when the maker documented pigment ink and document-security properties matter. Skip it if the G2 refill ecosystem or a published line-width figure is more useful.
Check uni-ball 207 Plus+ Black 0.7mm Gel Pens, 12 Count on Amazon Paid linkThe same ball size does not settle line feel
Both exact packs use 0.7mm balls and black gel ink, but the label on the package can be confusing. Pilot technical material calls its 0.7mm G2 medium and publishes a 0.32mm writing width, while the US retail listing may describe that tip as fine. uni-ball calls 0.7mm medium and does not publish a directly comparable line width on the current page.
Ball diameter is only one contributor to a written line. Paper coating, absorbency, pressure, angle and ink flow all change the mark. If a form has narrow boxes or a notebook has thin paper, test one pen on the real stock before committing to a large supply. Do not infer an exact line match from the shared 0.7mm number.
Ink priorities separate the two models
Pilot describes G2 as a refillable gel pen with a tungsten-carbide ball and visible ink level. uni-ball describes 207 Plus+ as using pigment-based Super Ink Plus+ that is water resistant, fade resistant and designed to resist document fraud. Those published properties give uni-ball the clearer security-oriented specification.
No pen can prevent alteration or damage in every situation. Water resistance is not waterproof storage, and fade resistance is not a promise of indefinite archival life under every light and paper condition. Follow the record-retention rules for the actual document, and use certified archival media when a governing standard requires it.
Drying claims need paper-specific testing
uni-ball says the Plus+ ink system is designed for enhanced drying speed. That is a manufacturer design statement, not a controlled comparison showing that it dries faster than this Pilot pack on every paper. Pilot does not provide a directly matched drying time in the cited technical information.
Left-handed writers and anyone annotating glossy paper should test their normal hand path, paper and room conditions. Allow fresh gel ink to set before highlighting or stacking. A pen that feels dry on absorbent copy paper may behave differently on labels, coated planners or thermal receipts, regardless of its general marketing description.
Refills change the long-term purchase
Pilot identifies BLS-G2 refills for G2, while uni-ball lists 70161 for black 207 Plus+. Buying refills can keep comfortable barrels in service and reduce the number of complete pens discarded. Verify tip size and color, because a refill family may contain several variants that fit the same general barrel.
Before ordering a box of refills, open one barrel according to its instructions and confirm the installed cartridge markings. Keep unused refills capped or packaged away from heat. A refillable design does not eliminate waste by itself; the benefit depends on actually keeping the barrel and purchasing the correct insert.
Grip and barrel preferences are personal
Pilot uses an ergonomic rubber grip and a transparent section that shows ink. uni-ball describes a seamless rubber grip and says the Plus+ differs from the standard 207 through its streamlined barrel and darker Super Ink Plus+ formulation. Neither manufacturer specification proves that one grip reduces fatigue for every hand.
For long notes, consider diameter, clip position, balance and the force needed to deploy the point. Writers with hand pain should avoid squeezing harder to control a slippery pen and may need a different barrel shape. Handle each model if possible, or start with a smaller quantity before standardizing an office supply order.
Choose the documented ink system, not hype
Choose Pilot G2 for its visible ink level, published 0.32mm line width and BLS-G2 refill platform. Choose uni-ball 207 Plus+ for its documented pigment-based security properties and redesigned seamless grip. Both exact purchases are twelve-count black 0.7mm retractable packs, so the comparison does not mix point sizes or colors.
The verified Amazon identifiers are B001GAOTSW for the Pilot G2 pack and B0B4BJR5X3 for the uni-ball 207 Plus+ pack. Confirm count, color and tip size at checkout. No handwriting preference, drying-time measurement, ink-yield test, archival certification, price, stock or personal-use claim is made.
