DunBong Pen Refills, Black Ink Refill Pack of 5, Replaceable Ballpoint Pen Refills, Medium Point Metal Refill (Black)

Very good quality. great value. Works well with my pen. Delivery was prompt.

I’ve been searching for refills for the Tiffany ballpoint for ages. Finally found these!

Great replacement for your pens

Aren't the landfills already packed with things? Why not just replace worn out ballpoint ink with these standard like refills. They aren't Waterman cartridges,; they work just as smoothly and the ink doesn't smear. Who will know the difference in my Canal Street Montblanc imitations?

If you are like me, I get anniversary, special events, commemorative type pens from my corporate employer. All of the pens are nice but they use Universal refills. I tried all different replacement brands and they all did not last long. Until I bought DunBong refills, out of the box the refill writes smooth and without problems. Highly recommended and satisfied with my purchase.

That's a "perfect" refill for my pen. When I bought this pen, it came with black ink, and I hate black ink. The pen manufacturer does not provide blue refills, so I was really happy to find this product. It works for the most part, but sometimes the cartridge fails and leaks ink, specially in very hot weather. As long as don't forget the pen inside the car on a hot day, or keep in in my pocket when I am outside for too long, it will be all right. Other than that it is a great product.

Clearly not cross inserts and I knew that when I bought them. They work well but don’t last long and they tend to come unscrewed often but for the price I can deal with it. They do right smooth and cleanly.

Son muy buenos y duraderos,solo me gustaria una caja con mas unidades,esa solo trae 5 unidades.
