Tombow Mechanical Pencil Lead Refills – 0.5mm

Tombow Mechanical Pencil Lead refills deliver exceptional break-resistance and smooth, low-friction graphite deposition for standard 0.5mm mechanical pencils. Formulated with high-density carbon, this premium Japanese lead produces crisp, consistent line definition with minimal smudging, making it an accurate choice for both technical drafting and everyday notation.

Available in two essential hardness grades to match your pressure and style:

1. HB: The classic mid-point balancing darkness and structural hardness. Ideal for versatile daily writing, clean note-taking, and standard layout sketching.
2. B: A slightly softer grade that yields a rich, dark line with a smooth glide. Perfect for expressive sketching, rapid notation, and those who prefer a darker marking with minimal downward pressure.
