Quality Quink Rollerball Pen Refills Fine Point 0.5 mm - Compatible with Parker (5 x Blue Ink)

fitted my parker pen perfectly

It is hard to write with them, it fills like scratching the paper. The one I put in the pen stopped working after a day.

Don't bother, they ain't a patch on genuine and the tip is so fine it would be better to use them to play darts with

Probably need a 0.7mm

Not a medium point as described but much finer. Result is a scratchy writing experience and not one I enjoy. Aside from that, they fit, they work.

Was looking for a generic replacement for the smooth Parker Rollerball. Not smooth or pleasant to write with, scratchy and ink slightly uneven. I've given one a fair bit of use to see if it improved. It didn't. I'll stick them in the drawer and spend the money on branded refills from now on. Worth a try but a didn't live up to expectations. Wouldn't buy again.

As with ball pen refills works well. Delivered in good condition, well packed and a worthwhile buy. Pity I wrote this review after one refil used, had I waited it would have been a different review completely, it turned out that the one I tried was the only one that worked. I would not buy again from this company again, in fact the refils fall far short of even being average

First and foremost, these are a compatible refill not a genuine Quink as the description implies. That's not important; what is important is they tend stop flowing mid-way through a word. Also, they do not seem to last very long. I'm no William Shakespeare but I'd expect to get more than two letters of one page from one refill. Guess the age old saying is still true: You get what you pay for. Buy genuine Parker and you won't go wrong.
