What does a spare cone do, and when do you need one?
A spare cone is an essential part of your Rotring Isograph technical drawing pen, as it determines the precise line width. When your cone is damaged, clogged or worn from intensive use, the line quality diminishes and you get uneven strokes. A new cone fully restores the optimal performance of your drawing pen.

Why choose specifically the 0.30 mm variant?
The 0.30 mm cone is designed for medium-weight detail work where you seek a balance between precision and visibility. This line width is ideal for technical drawings where you want to indicate details without lines becoming too thick, yet not so fine that they are barely visible on the drawing.

Recognition through colour coding
The grey/green colour coding of this cone ensures you can always identify the correct line width. Rotring uses this consistent colour-coding system for all 0.30 mm parts, making confusion with other widths practically impossible. This prevents frustration while drawing when you quickly switch between different line widths.

Practical compatibility tip
This spare cone is only compatible with Rotring Isograph pens and does not fit other brands or types of drawing pens. Always check reference number S0218250 when ordering to make sure you receive the correct part. Store spare cones in their original packaging to prevent damage.
