Parker Quink Roller Ball refill Fine Black S0168600
Suitable for all Parker roller ball pens
Fine grade - 0.5mm
My Prime has run out, but this one did not offer me Super Saver Delivery, so I had to pay £3 for 1st Class delivery, but for a box of 12, still a good deal! Next cheapest I can find for a box of 12 genuine refills was over £20!
Hope people find this useful.
