The Matomamaru-kun eraser by Hinodewashi has earned a dedicated following for its unique ability to "gather eraser shavings without scattering them," making it a beloved tool among students, artists, and professionals. Unlike traditional erasers that often leave behind a trail of small, scattered shavings, the Matomamaru-kun eraser effectively collects these shavings into a single, tidy clump. This ingenious feature not only simplifies cleanup but also keeps workspaces neat, making it especially popular in environments where cleanliness and organization are key. Since its debut in 1986, the Matomamaru-kun has maintained its reputation as one of Japan's most trusted and well-loved erasers.
