Parker Refill for Retractable Gel Ink Pens, Medium, Black (30525PP), Blue (30526PP) and Red (30529)

These refills are very poor quality.... they SKIP ...... just about as good as those freebee pens that you get at the bank !

I love the parker gel ink! smooth and just the right amount of ink flow

The ink in these does not flow consistently. I can usually get about three letters out before I have to scratch wildly at some scrap paper in a futile attempt to get it flowing again.

Great refill for some cleverly designed promotional pens that have very low quality ink cartridges

Black and red ones are working fine and smooth in writing, but both the blue ones feels empty and when they write it looks like normal ink not gel. Highly disappointed.

Blue and Black are nice gel refills, work great, ink flows smoothly. Red refills are less than stellar...for some reason, they arrived coated in something that was both sticky and greasy. Once cleaned, they operated fine, but the ink doesn't flow as nicely as the other two colors, and results in an uneven, thinner line.Five stars for blue and black. Minus one for the weirdness with the red refills.

Came as advertised. The only problem I found, was the red refills had a sticky feel to them out of the package (otherwise it would have gotten the 5th star).Edit: after using the blue gel ink briefly, they started to not flow smoothly. In lowering my rating by one star. The black and red gel ink still flow smoothly.

the red refills came without capstan the tips, dry ink, the others were fine.Initial quality poor then
