Questions and answers

Does the pen come with ink?
No. The Isograph ships without ink, so you need to buy rOtring-compatible pigment ink separately before first use.
What is the 0.13 mm tip best for?
It is the finest size in the Isograph range, meant for very fine line work on tracing paper. It is not suited to bold lines or rough sketching.
Can I use it on regular paper?
It works, but rOtring recommends tracing paper. Rougher paper wears the fine tip faster and can cause feathering with pigment ink.
How do I stop it from clogging?
Use it regularly and flush the tip with water when you stop drawing for a while. Leaving pigment ink to dry in a 0.13 mm point is the main cause of clogs.
Is $25.77 a good price?
That is the best new price across three stores as of November 5, 2026. Check the price history to see whether it usually sells higher.
Where is the rOtring Isograph Technical Drawing Pen 0.13 mm cheapest?
At Amazon, for $25.77, as of our latest check.
Where can I buy the rOtring Isograph Technical Drawing Pen 0.13 mm?
4 stores we checked sell it, including ProtoPens, eBay, Amazon, Craftelier.
