Pentel PEN50BBX 0.7 Mm Black Lead Refills 12-pack

Product Description

The PENTEL PEN50BBX Super Hi-Polymer lead refills are 0.7 mm diameter mechanical pencil leads engineered for consistent, dark, smooth lines across writing and drafting tasks. Each tube contains 12 individual lead pieces, and each piece is rated to write as far as a standard wooden pencil, making the box-of-12 format a high-output supply option. The high-density polymer composition resists breaking under normal writing pressure while maintaining a sharp, clean line. This box unit of measure contains 12 tubes, making it well suited for office supply rooms, classrooms, or field service kits where reliable writing consumables need to be stocked in quantity.

These lead refills are intended for use in standard mechanical pencils that accept 0.7 mm leads. The 0.7 mm diameter is one of the most widely used sizes across general writing, note-taking, technical sketching, and form completion. The black color and high-density formulation produce consistent line darkness suitable for scanned documents, printed forms, and hand-drafted layouts. Packaged in a box of 12 tubes, this format is appropriate for procurement in office, school, and professional trade environments where mechanical pencils are standard issue.

Installation Notes

Loading lead into a mechanical pencil does not require tools. Retract or remove the existing lead, advance the lead feed mechanism, and insert the new lead piece according to the pencil manufacturer's loading procedure. Avoid forcing lead into a jammed feed mechanism, as this can cause breakage inside the barrel.
