SEED

Founded in Osaka in 1915, Seed Co., Ltd. (株式会社シード) is a specialist manufacturer dedicated almost entirely to the mechanics of correction. The company transformed everyday stationery in the 1950s by developing the world’s first plastic eraser, replacing brittle natural rubber with a clean, polymer compound that lifts graphite without tearing delicate paper fibers. Seed has since earned a reputation for precision erasing tools, from iconic desktop blocks to specialized instruments like the ultra-slim Slendy+ series, making dependable, low-dust erasers engineered for technical drafting, student notebooks, and daily desk work.
