Parker Gel Rollerball Refill for Roller Ball Pens Medium Point Blue Ink 12-Total refills

They did not fit my Parker pen but did fit my cross pen. I would not buy this product again.

I use this blue gel ink because I want to be able to tell originals from copies of laser prints. It works with laser copiers and scanners. This blue gel does not produce lighter prints. I will buy more when needed.

I have opened 3 of the 6 - 2 packs so far. Only one refill has worked. Very disappointed as I have used these refills for years prior to this order.

By far the best writing pen refill !! Never a issue !! Writes Perfectly !!

Perfect! The best way to use the Parker Jotter

Pen collector and pleased with item. Will return.

Perfect.

thanks !
