Sun-Star SHARM Rotating Mechanical Pencil Eraser

Sun-Star SHARM Rotating Mechanical Pencil Eraser (0.5mm)

The Sun-Star SHARM combines precision drafting and fine-point erasing into a single, seamless writing instrument. Engineered in Japan by Sun-Star Stationery, this 2-in-1 rotary tool pairs an anti-break 0.5mm mechanical pencil mechanism with an integrated 2.0mm mono stick eraser. A quick twist of the upper barrel seamlessly switches between drafting mode and correction mode, providing students, architects, and designers with immediate error correction without needing to flip the pen or carry a separate eraser block.
