The best pen for most teachers is the Paper Mate Flair felt tip: a 0.7 mm point that writes bold, readable comments on worksheets, comes in a 24-color pack for color-coded feedback, and uses water-based ink that Paper Mate says won’t bleed through paper. But a teacher’s day has at least four different writing jobs, and no single pen does all of them well. This guide matches one pen to each job, from grading a stack of essays to the whiteboard at 8 a.m.

How we chose
We didn’t test these pens in a classroom. We compared manufacturer specs and Amazon listing data (point size, ink type, refill options, pack size) and read the owner reviews on each listing, looking for the problems that only show up after weeks of use. Ratings below are the aggregate Amazon figures shown on each listing when we checked in November 2026. We left out prices because they change weekly; use the buttons to see the current one.

Should you grade in red? What one study found
Before picking a grading pen, it helps to know about a 2010 paper in the European Journal of Social Psychology by Abraham Rutchick, Michael Slepian and Bennett Ferris. In one experiment, people correcting an essay with a red pen marked more errors than people using a blue pen. In another, 129 participants graded the same one-page essay: the red-pen group gave an average of 76.2 out of 100, the blue-pen group 80.0.
Two caveats matter. The participants were students acting as graders, not trained teachers, and the authors say other explanations are possible. Still, the finding is cheap to act on: if you want feedback that reads as coaching rather than correction, grade in green, purple or blue, and save red for the few marks that must stand out. That is a big reason the top pick below is a multicolor pack.
1. Paper Mate Flair Felt Tip: best for grading
Who it’s for: teachers who write comments on worksheets, quizzes and essays and want them readable at a glance. Skip it if you need to fit notes into tiny answer boxes; a 0.7 mm felt tip writes a wider line than a 0.5 mm gel pen.
Flair is a familiar name in teacher-supply aisles, and the listing numbers back that up: 4.8/5 from more than 78,000 Amazon ratings. The 24-count pack gives you enough colors to assign one per class period or one per feedback type (green for strengths, purple for revisions).
- 0.7 mm medium felt point leaves a bold line that students can read without squinting
- Water-based ink that Paper Mate says resists smearing and won’t bleed through paper, so the back of a double-sided worksheet stays clean
- 24 assorted colors in one pack, which makes color-coded feedback practical
- Black-only packs exist too, if you want a matching pen for forms
Cons:
- Capped, so caps go missing in a busy classroom
- Not sold as refillable; when a pen dies, it’s done
- Water-based and not advertised as waterproof, so keep it away from wet desks and spilled coffee
2. Paper Mate InkJoy Gel: best for planners and color-coding
Who it’s for: teachers who keep a paper lesson planner, a gradebook or a color-coded calendar. Skip it if you want one refillable pen you keep for years.
InkJoy Gel is the smoother, more saturated cousin of the Flair. Paper Mate says the ink dries 3x faster (its asterisked comparison, without naming the benchmark on the listing), which matters when you close a planner right after writing. The 14-color assortment covers more than enough subjects or class periods for a weekly spread. Rated 4.8/5 from more than 68,000 Amazon ratings.
- 0.7 mm gel point that writes a solid, vivid line on planner paper
- Fast-drying ink claim from the maker, useful for left-handed teachers too
- Ergonomic grip that wraps the whole barrel
- 14 colors in one pack for subject or period coding
Cons:
- Only one point size (0.7 mm) in this pack, which can be wide for small planner boxes
- The “3x faster” figure is Paper Mate’s own claim, not an independent measurement
- Planner paper varies a lot, so test a color on the back page before you commit a whole year to it

3. Pilot G2 Extra Fine 0.5 mm: best for margins and small boxes
Who it’s for: math and science teachers marking cramped work, anyone who fills in rubric boxes or attendance grids. Skip it if your comments need to be read from across a desk; the 0.5 mm line is thin.
The G2 solves the felt tip’s main weakness: space. This 10-pack has assorted colors, a retractable tip (no caps to lose), and it takes standard G2 refills, so a favorite color can live on. Rated 4.8/5 from more than 2,400 Amazon ratings.
- 0.5 mm extra-fine point fits notes between lines and inside small grid cells
- Retractable click design, so nothing to lose and nothing to dry out with the cap off
- Refillable with Pilot G2 refills (sold separately)
- Contoured rubber grip for long grading sessions
- Pilot says G2 is its longest-lasting gel ink (based on its own data on file)
Cons:
- Fine lines are harder to read for younger students and from a distance
- Refills cost extra and are sold separately
4. Pentel EnerGel RTX: best desk pen for the teacher
Who it’s for: the teacher who wants one good pen for permission slips, parent notes, report-card comments and signatures, and who smudges gel ink. Skip it if you lose pens weekly; a refillable metal-tip pen makes more sense when it stays on your desk.
Pentel describes the EnerGel’s liquid gel ink as fast-drying and suited to left-handers, with no smears or globs. The RTX adds a stainless steel tip, a latex-free grip and a limited lifetime warranty, and it takes any EnerGel refill in any size or color. This 10-pack in assorted colors is rated 4.8/5 from more than 2,200 Amazon ratings.
- Fast-drying liquid gel ink, a real help if your hand drags across fresh writing
- Refillable with any EnerGel refill, including 1.0 mm bold if you want a heavier line later
- Latex-free grip, worth knowing in a school with latex allergy policies
- Limited lifetime warranty from Pentel
Cons:
- The RTX line is listed as not water resistant, so it isn’t the pen for outdoor duty or field-trip forms
- Costs more per pen than a bulk pack of stick pens; it’s a pen to keep, not to lend

5. BIC Round Stic Xtra Life (60-pack): best loaner pens for students
Who it’s for: every teacher who hears “Can I borrow a pen?” five times a day. Skip it if you want vivid color or a smooth gel feel; this is a basic ballpoint.
The pen jar on your desk doesn’t need good pens. It needs a lot of pens that work. BIC calls the Round Stic Xtra Life the No. 1 selling ballpoint in the US (citing NPD sales data) and says it writes 90% longer on average than the Paper Mate InkJoy 100 stick pen. The 60-count box is rated 4.7/5 from more than 72,000 Amazon ratings.
- 60 pens per box, enough to stock a loaner jar for a semester
- Translucent barrel shows how much ink is left
- 1.0 mm medium point with a tungsten carbide ball
- Owner reviews on the listing mention ink that doesn’t smear after writing
Cons:
- Non-refillable, as BIC states on the listing
- This pack is black only (blue is a separate listing)
- A ballpoint line is paler than gel, so it’s a poor choice for your own feedback

6. EXPO Low Odor Dry Erase, Chisel Tip: best for the whiteboard
Who it’s for: any teacher with a whiteboard and a room full of noses. Skip it if you mostly write fine details on a small lapboard; get the EXPO fine-point version instead.
EXPO formulated these markers to be low-odor for classrooms, and the ink is AP-certified nontoxic and conforms to ASTM D-4236. The chisel tip writes a broad line for headings or a narrower one when turned on its edge. The 12-pack includes black, red, blue, green, orange, brown, plum, purple, aquamarine, pumpkin, lime and pink.
- Low-odor ink designed for classrooms
- AP-certified nontoxic, conforms to ASTM D-4236
- Chisel tip gives two line widths from one marker
- Erases with a dry cloth or an EXPO eraser
- Twelve colors, so you can match the grading-color system on your board
Cons:
- One teacher reviewing the listing found that students pressing hard loosened the tips, and that darker colors erased less cleanly and left ghost lines
- Light colors such as lime and pink are harder to read from the back row
- Ratings vary across the listing’s versions, so there’s no single figure we can quote
An owner tip from the same listing: store markers vertically with the cap side down to keep the tip wet.
Which pen for which teaching job
Most teachers end up with a small kit rather than one pen. Here’s how to build it based on what you actually write in a week.
If you grade essays or long-form work
Use the Flair. The bold felt line reads well next to handwriting, and the color pack lets you follow the red-pen research: green or blue for routine comments, one stronger color for errors that must be fixed. If your students’ work is double-sided on thin paper, test one page first.
If you grade math, science or multiple choice
Use the G2 0.5 mm. Margin math and bubble sheets leave little room, and a fine retractable gel pen keeps marks tight. Add a Flair for the score at the top.
If you keep a paper planner
Use InkJoy Gel for color-coding by subject or period, and the G2 0.5 mm for small daily boxes. Need to move lessons around often? Our best erasable pens guide covers pens that let you rewrite a week without crossing out.
If you sign forms and write to parents
Keep one EnerGel RTX on your desk in black or blue. It looks more finished than a stick pen, dries fast, and you refill it instead of replacing it. If your school specifies an ink color for official forms, follow that rule.
If students keep borrowing pens
Fill a jar with BIC Round Stics and stop lending your good pens. At 60 per box, losing a few a week doesn’t matter.
If you teach at a whiteboard
Low-odor chisel-tip markers, stored cap down. Pair them with a dedicated eraser so you don’t smear ink around with a tissue.
FAQ
What pens do most teachers use for grading?
In teacher threads we read, the same names keep coming up: Pentel EnerGel, Pilot G2, Paper Mate Flair and InkJoy. They write bold, readable lines with little pressure. Felt tips suit written comments; fine gel pens suit math and small boxes.
Is it bad to grade in red pen?
Not bad, but not neutral either. In the 2010 Rutchick, Slepian and Ferris studies, people using red pens marked more errors and gave lower essay grades (76.2 vs 80.0 out of 100) than people using blue pens. The participants weren’t trained teachers, so treat it as a nudge, not proof. Many teachers switch to green or purple for routine feedback.
What is a good gift pen for a teacher?
A color pack they’ll use up (Flair or InkJoy) is the safe choice. For something they’ll keep, a refillable pen like the EnerGel RTX with a few extra refills lasts longer than a mug. Novelty “Best Teacher” pens look nice but rarely become the pen a teacher reaches for.
Which pen is best for left-handed teachers?
A fast-drying ink matters most. Pentel markets EnerGel’s liquid gel as smear-resistant and suited to left-handers, and Paper Mate says InkJoy Gel dries 3x faster.
