During normal writing no inky fingers should arise; if between the front metal ring and grip section ink emerges, a defect is to be assumed that cannot be unambiguously diagnosed without inspection. It is recommended to present the writing instrument to a Montblanc boutique or to Montblanc service. The repair by Montblanc service worked reliably in the specific case; an initially issued invoice was generously handled in the boutique. If after filling ink first emerges, this can at least temporarily be controlled by carefully wiping the area (e.g. with a tissue); if fine scratches later arise on the grip section, these can be caused by putting on or screwing on the cap.
