Plastic Ink Cartridge Kit 10Pcs Thermal Erasable Pen Refill Cartridges Dark Blue Ink for Fountain Pens

This 3.4mm Replaceable Ink Cartridge Thermal Erasable Pen Refill is designed for convenient and clean writing. Utilizing advanced thermal erasable technology, the ink is crafted from a thermosensitive microcapsule water-based color paste. This unique formulation allows handwriting to vanish when exposed to heat above 60 degrees Celsius and reappear when cooled below -15 degrees Celsius, enabling repeated writing and erasing cycles without leaving any residue on the page. The system supports hassle-free edits, making it an excellent choice for notes, drafts, and planners. Each cartridge provides a reliable ink flow for consistent writing performance. The universal 3.4mm size ensures these refills are compatible with a wide range of fountain pens that accept this standard cartridge, offering a practical alternative to traditional bottled ink. Available in classic black, blue, and dark blue shades, these cartridges are a versatile accessory for various writing instruments.
