The quality of these Swiss-made rollerball pens is evident. What is not so obvious is the quality of the refills. Caran d'Ache have developed and refined their rollerball refills with the result that their rollerball pens give a level of writing comfort not dissimilar to that of a good fountain pen.
Caran d'Ache rollerball pens also accept the Caran d'Ache fibre tip refills, which are available in both medium and fine sizes.
All of these rollerball pens come with the Caran d'Ache international guarantee.
