Key item features

During use, the thermal erasable pen leverages thermosensitive microcapsules that enable handwriting to vanish above 60°C and reappear below -15°C, allowing for repeated writing and erasing without leaving residues or damage.
The built-in eraser uses frictional heat to cleanly remove marks without crumbs or paper damage, providing a tidy and hassle-free editing experience compared to chemical erasers.
Our pens feature a sleek and dependable ink flow with low-volatility ink, ensuring consistent and clear writing. If the nib dries out after extended storage, simply dip it in a nib moisturizer to restore optimal performance.
These universal 3.4mm replaceable ink cartridges are available in black, blue, and dark blue, compatible with many fountain pens. They offer a convenient, cost-effective, mess-free alternative to traditional ink bottles for long-term use.
Designed with a double-function, the pen combines a writing nib and erasing head, allowing seamless correction of mistakes and rewriting without additional tools—ideal for precise editing and detailed work.
