When do you use 0.5 mm refill leads?
Refill leads are the replaceable graphite cores for your mechanical pencil. You need these leads when your current leads have run out or broken. With a diameter of 0.5 mm, these leads are ideal for precision work such as technical drawing, architectural sketches or detailed writing where you need thin, crisp lines.

Why choose hardness grade H?
The H hardness stands for "hard" and produces lighter, finer lines than soft graphite varieties. This grade is perfect when you are making accurate line drawings or when you want to prevent your drawing from smudging. H leads wear down more slowly than soft varieties, so you can keep working for longer without inserting new leads.

What does HI-POLYMER SUPER mean for your work?
Pentel's HI-POLYMER SUPER technology produces leads that are stronger than ordinary graphite leads. This means fewer breakages during use, which is especially important with the thin 0.5 mm diameter. You can apply more pressure without the lead breaking, making it possible to maintain a constant line width.

Practical tip for use
These 12 leads fit any mechanical pencil suitable for 0.5 mm leads, which is the standard size for most mechanical pencils. Keep the spare leads in the original packaging to prevent breakage. The reference code C505-H helps you reorder exactly the same specification.
