Follow this order
1. Identify ballpoint, rollerball or fountain pen. 2. Note the collection and model. 3. Find the previous refill reference. 4. Check that pairing against the official listing. 5. Select colour and tip size within the confirmed format.
An unknown result is useful too
If the model or reference is missing, the correct result is “compatibility unconfirmed”. A collection may include several systems and formats. Its name alone cannot populate a reliable compatibility table.
