Montblanc grants on its own repairs six months' liability for defects; within this period one should immediately complain; afterwards the service flat fee applies again. Cause of a hard script is often a too narrow nib slit, e.g. because on reinserting the nib the feed was pressed together. Here professional setting of the nib helps, which most boutiques do not perform themselves but pass on to specialised nib workshops. A correctly set nib already brings ink onto the paper without writing pressure; more pressure would then overstrain the feed. Collectors report that setting is an experience-dependent intervention depending on the user's typical writing pressure.
