The advanced ink flow system ensures even distribution without blotting, ideal for detailed note-taking, exam revisions, office documentation, and daily journaling.
• Important Temperature Notice: Please note that these heat erasable gel pens use temperature-sensitive ink that automatically fades or disappears completely in high-temperature environments. Avoid placing your written notes, notebooks, or the pens themselves in direct sunlight, near heaters, inside cars on hot days, or any area with sustained high heat, as the ink will vanish without friction. For this reason, these pens are not suitable for official exams, legal documents, signatures, checks, or any permanent records where long-lasting, non-erasable writing is required. They are designed for daily notes, homework, drafts, planners, puzzles and temporary writing only.

Click-Retractable Convenience: Unlike capped erasable pens that are easy to lose caps and cause tip damage, our click-design friction pens allows one-handed operation—quickly start writing or retract the tip with a light click.

The built-in eraser makes mistakes vanish instantly, keeping your notes and homework neat. 0.5mm Precision Smooth Writing: Compared to 0.7mm thick-tip competitors, our 0.5mm bullet tip delivers consistent, skip-free lines for clear, legible writing. Wide Applications Ideal for daily note-taking, student homework, exam revisions, office documentation, journaling, essay revision, to-do list updates, Sudoku/crossword solving, and sketch refining.

Detailed Specifications Package Includes: 20 click-retractable erasable gel pens + 20 matching refills Note: Please keep in mind that the thermo-sensitive ink in these pens can disappear on its own in high-temperature conditions. Do not place your notes or pens in direct sunlight, hot cars, near radiators, or other warm areas, as high heat will make the handwriting fade away completely. Due to this special feature, these erasable pens are not suitable for official tests, legal documents, important signatures or permanent records. They are ideal for daily writing, school assignments, office memos, sketching and reusable puzzle books.
