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

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

These worked very well

Received these refills quickly and they fit just fine in my twist-to-extend pens. The springs in my pens are still in good shape so not a problem having refills without the spring. I use one of the pens to write checks and have found the performance great so far in terms of line thickness, smooth flow and non-smear. It was good to be able to find refills at a reasonable price especially since it's near impossible anymore to find refills in stores.

Great refill for a pen until it wasn’t. Second cartridge exploded in the pen but the pen was taken on flights so maybe it was the pressure? Not sure!

These are exactly what I needed and they write nicely

Excellent writing ink! Excellent Seller! Fast Shipping! Excellent price! Thank-you! Happy Holidays!!

Pretty decent. However, it does have problems with writing small, especially with sharp corners, jams up every time I try to write a 5

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.
