Famously known in Japan as the \"Keshizumi\" (消炭 - Charcoal Black \/ Faded Black) edition, its design is inspired by the quiet, comforting image of charcoal embers cooling after a long fire. To achieve its beautifully ink-dark aesthetic, this is the only model in the regular lineup featuring a matte black coated wire clip instead of the standard polished silver metal, creating a flawlessly uniform, tactical look.\u003c\/p\u003e\n\u003cp\u003eThe uni-ball one F is an ergonomic upgrade from the everyday plastic gel pen.
