Parker Rollerball Pen Original Quink Ink Refills - 0.7mm Medium Tip - Blue Ink - Pack of 4

Have had difficulty using these, the ink stops flowing.

Excellent product & very fast delivery.

If like me you like a good pen, ideal refills fir such.

I have had a rollerball pen for many years. The ink does not smear and smudge like an ordinary biro.The ability to bulk buy refills is great as I always seem to run out of ink at important times.

First cartridge, although in sealed package, was empty. Second cartridge from same package run empty after just one week. Either the cartridges were defective or they were fake.
