Japanese stationery brand SEED brings the convenience of a retractable pen to the humble eraser. The Radarknock Blue features a push-button mechanism that keeps the eraser protected inside its barrel and ready to use whenever you need it.
Its distinctive crescent-shaped eraser offers both a fine edge for precise corrections and a wider surface for everyday erasing. The slim 5 mm tip provides excellent control when removing individual letters, numbers, or small details, making it ideal for students, designers, architects, engineers, and anyone who works regularly with pencil.
Designed for long-term use, the SEED Radarknock features a replaceable eraser refill and a convenient clip for attaching it to a notebook, pocket, or pencil case. Compact, practical, and easy to handle, it keeps corrections quick and your workflow uninterrupted.
