Pentel PENC505H Lead Refill 0.5mm Black 12-piece

Product Description

The PENTEL PENC505H is a Super Hi-Polymer mechanical pencil lead refill in 0.5mm diameter, formulated to produce consistently dark, smooth lines across all standard mechanical pencils that accept 0.5mm lead. Each individual lead stick is engineered for high tensile strength, reducing breakage during normal writing pressure. The refill is designed to lay down uniform graphite density from the first stroke to the last. Each tube contains 12 lead pieces, and the writing length per piece is comparable to one standard wooden pencil, giving the full tube the output equivalent of 12 wooden pencils. This product is sold as a tube of 12 pieces, with a unit of measure of one tube.

The PENC505H is intended for use in mechanical pencils requiring 0.5mm diameter lead. It is suited for office environments, drafting work, classroom use, and general writing tasks where consistent line quality and lead durability are required. The 0.5mm diameter is a standard size widely used in both professional and educational settings. The black color designation confirms standard graphite output appropriate for everyday writing, sketching, and technical notation. Trades and field professionals who carry mechanical pencils for marking, notation, or site documentation will find the high-strength formulation reduces interruptions from lead breakage.

Installation Notes

Loading mechanical pencil lead requires no tools. Retract or remove the existing lead before inserting the new piece through the pencil tip or top-loading chamber per the pencil manufacturer's instructions. Avoid applying side pressure when inserting lead to prevent breakage. Keep unused lead stored in the tube to protect against moisture and breakage.
