Sized at 0.9 mm diameter with HB hardness, these leads are engineered for consistent dark lines with smooth, even density across both writing and drawing applications. The Super Hi-Polymer formula produces strong leads that resist breaking under normal writing pressure, reducing interruptions during use. Each 12-piece tube delivers writing length equivalent to 12 standard wooden pencils, making this format practical for high-volume users in office and school environments.\u003c\/p\u003e\u003cp\u003eThese refills are suited for everyday writing tasks in office, classroom, and drafting settings where 0.9 mm HB leads are the specified size. The HB grade balances darkness and smear resistance, making it a general-purpose choice for note-taking, forms, and freehand sketching. Sold as a box of 12 tubes, this format is well suited for supply rooms, purchasing departments, and professionals who maintain stock of consumable writing supplies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.9 mm diameter fits mechanical pencils requiring 0.9 mm lead\u003c\/li\u003e\n\u003cli\u003eHB hardness delivers a balance of dark marking and clean erasability\u003c\/li\u003e\n\u003cli\u003eSuper Hi-Polymer formula resists breakage during normal writing pressure\u003c\/li\u003e\n\u003cli\u003eEach 12-piece tube equivalent to 12 wooden pencils in writing length\u003c\/li\u003e\n\u003cli\u003eBox of 12 tubes provides bulk supply for extended use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in mechanical pencils that accept 0.9 mm diameter lead refills with HB hardness.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eLoading lead refills into a mechanical pencil does not require tools.
