Frequent skipping is not normal and should lead to a complaint at the boutique; one's own everyday paper should be brought along, since writing behaviour on test paper deviates significantly.

A crookedly seated nib is a clear defect and likewise complaint-worthy. Before concluding a production fault, it should also be checked whether the cartridge sits correctly and whether someone else can write with the pen without problems. For storage there are Montblanc cases from about 70 euros, often with integrated note pad and credit-card slots.
