DONGA erasable pen uses friction-based erasable ink technology to allow handwritten text to be erased cleanly from paper — combining the permanence-on-demand of a ballpoint with the correctability of a pencil. A Korean stationery brand with established production heritage, now available internationally through DEMORE. Designed in Korea, manufactured in China.
The erasable pen occupies a specific consumer need that neither regular ballpoint nor pencil satisfies perfectly: permanent-looking ink that can be cleanly removed when a mistake is made. Pencil is erasable but produces a different writing feel and aesthetic; conventional ballpoint is permanent but cannot be corrected. Friction-erasable ink technology resolves this: special ink that writes like a ballpoint but becomes invisible (not truly removed) when heat from friction is applied via the eraser tip.
DONGA is a Korean stationery brand with strong production heritage that has applied this technology to a pen designed for the school, office, and institutional market. The product is a consistent seller across Asian markets and translates well to international retail where the category has become established. Korean pen manufacturing quality — smooth writing feel, reliable ink flow, consistent erasing — is the key competitive parameter in this category.

The DONGA erasable pen writes with the same feel and appearance as a standard ballpoint — smooth, consistent ink flow, clear line. No visual difference from a conventional pen during writing.
When the rubberised eraser tip is rubbed across the ink, friction generates localised heat. The heat causes the thermochromic ink to become colourless — appearing as if it has been erased cleanly, without the smearing of wet erase or the paper damage of abrasive erasing.
Because the erasing mechanism is heat-based, DONGA erasable pen writing becomes invisible if exposed to high temperatures (sun exposure, washing). For archival or legal documents, conventional permanent ink is more appropriate. Erasable pen is ideal for school notes, drafts, planning, and everyday writing.
The primary consumer segment is students — for whom an erasable pen that writes like a proper pen (not a pencil) but corrects mistakes is an obvious upgrade. School stationery sections in value retail, supermarkets, and stationery chains are the core channel.
Office stationery retail and wholesale for the professional who makes notes, plans, and works through drafts where erasability is useful — calendars, planners, project notebooks, and similar everyday office writing contexts.
Value retail stationery sections where erasable pens are an established SKU with strong consumer recognition and consistent velocity. Korean stationery quality at accessible price points is a natural value retail proposition.
