Our Premium Rollerball refill is manufactured by Beaufort Ink in the UK.  We have tested these refills and find them to be as good (if not better) than genuine high-street names.  The refills are manufactured to the highest standard, feature Swiss made components and an exceptionally long writing life. These refills feature tungsten carbide balls for smooth, non-skip writing performance.  They also have stainless steel nibs for longer life and corrosion resistance.
