Editorial approach
eMontblance31.10.2026The catalogue distinguishes ballpoint refills and Small formats. Check which one your instrument requires. Matching colour and tip size does not prove that two refills share the same format.
Once the format is confirmed, compare the reference, colour, stated tip size and number of units in the pack. Keep these details for your next replacement instead of relying only on a photograph.
