Thermosensitive gel ink (blue) formulated for erasability; stainless-steel rollerball tip (commonly 0.5–0.7 mm tip options); durable plastic barrel and click/cap mechanism; integrated rubber friction eraser. Materials may vary slightly by model — check packaging for specific tip size and part details.

1. Click or remove cap to expose the rollerball tip and write as normal.
2. To erase, rub the built-in rubber eraser over the inked area — friction generates heat that makes the ink disappear cleanly.
3. If needed, write again over the corrected area once the surface is clear.
4. Replace cap or retract the tip when not in use to prevent drying and protect the tip.

Ideal for students, teachers, planners, bullet-journalers, office professionals and anyone who needs neat, editable handwriting. Great for classrooms, offices, notebooks, planners and everyday writing tasks where tidy corrections matter.

Not suitable for permanent records or legal documents — ink is thermosensitive and can be erased by heat or friction. Avoid exposing written pages to high temperatures (for example, leaving in a hot car or near heat sources) as ink may fade or disappear. Keep pens capped or retracted when not in use, store at room temperature away from direct sunlight, and keep out of reach of small children. Do not ingest ink. For archival or long-term labeling, use a permanent pen.
