Gullor 5 PCS Refills Duke 0.5mm Pen Refill Length 111mm Refills Black Pen Refills

I ordered refills for a pen I was gifted by a friend. I was really worried about finding refill cartridges that would fit my pen exactly. When my order arrived, I compared it to my pen and it looked like it would fit. It did!I am ultra pleased with this ink refills. The ink flows smoothly and doesn't skip or scratch at the paper. The ink is dark while still giving a thin, elegant line. I have found this pen gives this smoothest line when it has some cushion underneath. I love how my pen glides across the paper. My favorite pen is back in business!

These Refills fit my Duke pen just fine, but they write a little scratchy. The ink is quite fluid and comes out more like a fountain pen than a ball point.I have only used one of the refills so can't be sure they are all the same.

I got some random promotional Duke pens really cheap at a convention, and bought these because all the pens had nearly empty reservoirs with the 0.7mm tip (which bleeds everywhere because I write with a lot of force. I feel almost like I'm trying to paint with the larger tips, super fast and light strokes, because the ink comes out so fast.) These fine tip refills are perfect for me; they allow me to use my normal writing style with some amazing pens, and have the end result look fine.

Not smooth. A little scratchy.

Received in great condition and they work beautifully. Put one in my pen and stored the others in my desk drawer since they have caps on the ends to keep them from leaking or drying out.

These refills are exactly as advertised and the company shipped them within a week from ordering. I am currently using two refills, and the ink is dark and smooth. Very pleased!

They arrived on schedule and work great. Thank you.
