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

I've ordered multiple times to refill a pen I received as an award. They fit well and last long.

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.

These worked very well

This pen refill fit my pen perfectly. However, the ink flow is spotty. It will stop flowing mid-word. Scribble off to the side and it starts flowing again. Kind of annoying.

These are exactly what I needed and they write nicely

great

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.

Great

The items were exactly as described on the listing. Great product ! They fit the pen perfectly. This option was a lot cheaper compared to purchasing an “original” refill for the pen. 5 Stars for the product and service.

These refills work well and it was so nice to find blue ink refills. I was able to replace two different pens that needed refills. Would recommend them. Make sure you pull that little plastic bulb off the bottom. Ink flows nicely.

Good product.

Work well

Fit hood. Work good.
