Technical pen work demands absolute consistency; that's where these replacement points matter. Koh-I-Noor engineers these .3mm nibs from hard chrome stainless steel to maintain precise line weight through extended use with lettering devices and templates. The nib sleeve design ensures stable ink flow while protecting the delicate point during repeated contact with template edges, critical when technical accuracy depends on every line matching exactly.

Chrome plating over stainless steel construction resists wear from friction against metal and plastic guides, extending point life significantly beyond unplated alternatives. This durability proves essential for architectural drafters and technical illustrators who work through template sets daily. The .3mm width provides fine detail capability while remaining robust enough for production work.

These points work reliably on both paper and cloth surfaces, maintaining consistent ink delivery across different materials. When your existing Rapidograph point shows wear or damage from template work, these replacements restore your pen to original performance. Keep spares on hand, technical deadlines don't accommodate waiting for replacement parts to arrive.
