PILOT Frixion Ball Slim 0.38mm is the slimmest and finest-writing pen in the Frixion series, designed for precise, detailed notes without bulk. With an ultra-fine 0.38mm tip, this pen is perfect for small handwriting, textbook annotations, planners, and tight notebook spaces. Its slim, clipless body keeps your pencil case light and organized, allowing you to carry multiple colors effortlessly. Equipped with Frixion’s thermo-sensitive ink, writing disappears when rubbed with the built-in eraser at the back. Friction heat turns the ink colorless — without eraser dust or messy residue. Clean, smooth, and satisfying. The pen features a side slide-knock mechanism for quick operation, and the transparent body adds a playful, colorful look to your everyday writing tools. Note: Frixion ink is erasable and is thermo-sensitive. Do not use on official documents, certificates, or materials that must not be altered.
