20PCS Pack Ink Refill 3.82 inch Ballpoint Pen Refill for JASON YUEN Brand Desk Ballpoint Pens (3.82 inch, Blue)

April 2018 - Quality seems good. But at 2.75" long, too short for my Swarovski Crystal Starlight Ballpoint pen. My original ink cartridge in the pen is 11.8 cm long (4 11/16".) Still looking for that size refill!June 2018 - updating my review from four to five stars. These refills do fit the Swarovski Crystal Starlight Ballpoint pen. Here's how to do it: Take the black plastic cap off this refill. Take the existing ink cartridge out of the pen. Pull it apart at the seam and discard the short writing tip. Plug the refill into the remaining half of the original ink cartridge until it won't go any further. Re-install ink cartridge in the pen.

I bought a Swarovski pen in Austria. Once home I had a tough time finding a store that carried the refills. I was so happy to find them on Amazon because I usually need a refill every 2 - 3 weeks.

These refill cartridges work but are just long enough to be usable. The cartridge must be pushed down an into place and I've had to adjust the cartridge periodically after use. All in all -- they work.

Item is as described. Works perfectly with the pens previously purchased.

I have a pen that I love, but was worried about finding refills. These were the perfect match and can use my pen for years to come. Product delivered within timeframe.

Did not work on my Swarovski pen!

Fit perfectly in my pen.

If you have that pen you love and it's gone dry, this was the only source I found for these.

Parecía una excelente oportunidad por el precio, pero la calidad de la escritura es malísima, la tinta parece que está por secarse y pinta muy mal

You can buy these refills in the color you want and interchange them between red, black and blue for the 2 pack LED lighting ballpoint pen.

great value
