Uni-ball R:E Erasable Gel Pen 0.5mm vs Paper Mate Erasermate Retractable

Buy the Uni-ball R:E if you want fine, dark gel lines and clean erasing for notes and sketches. Buy the Paper Mate Erasermate if you want a sturdy, refillable-feeling ballpoint that survives rough handling and writes on most paper. The R:E writes smoother and erases better, but its heat-sensitive ink fades above 140°F and can reappear in deep cold. The Erasermate is a medium 1 mm oil-based ballpoint with a rubber grip; its erasing is rougher and its line is broader.

  • Choose the Uni-ball R:E if you take dense notes, draw, or need a fine 0.5 mm line you can rub out cleanly without dust or wear on the eraser.
  • Choose the Paper Mate Erasermate if you want a medium 1 mm ballpoint with a rubberized grip and a pocket clip that handles everyday, rougher use.

Questions and answers

Which is better for taking notes in class?
The Uni-ball R:E. Its 0.5 mm gel line stays legible in small spaces and erases cleanly for corrections. The Erasermate's 1 mm line is broader and its erasing is rougher.
Which lasts longer?
The Erasermate's oil-based ink and plastic body hold up to rough daily use, and its eraser does not wear down like a rubber eraser. The R:E's eraser never wears out, but its ink is sensitive to heat and cold.
Is the Uni-ball R:E worth stepping up to?
Yes if you write small, draw, or erase often. The fine gel line and dust-free friction eraser are a real step up for note-taking. Skip it if you need ink that survives heat or cold.
Can I use the R:E on legal documents or envelopes?
No. The maker advises against signatures, legal documents, and addressing envelopes because the heat-sensitive ink can fade. Use the Erasermate or a permanent pen for those.
Which is better for left-handed writers?
The Erasermate. Its oil-based ink dries quickly and is smear-proof, which helps when your hand drags across the page. The R:E's gel ink can smudge before it dries.
Does the Erasermate erase as cleanly as the R:E?
No. The R:E's friction eraser turns the ink invisible with no dust. The Erasermate rubs ink off the paper surface, which can smudge and leave residue.
