4.5'' Ballpoint Ink Pen Refills for Twist Pens,1mm Medium Tip, Compatible with Cross Pen Refills (8513)(10 Pcs Black Ink)

They are easy to replace, easy to use and superb quality! Just as good as the name brand for my Cross pens but so much less expensive. Works perfect for me!

I could not find these pen refills locall so was apprehensive ordering them. But They fit my pens and work well!

Inexpensive compared to OEM Cross refill.I had several of the twist to extend pens including three Cross pens and some other nice hefty pens I got. Used 8 of the refills by the time I was done. Happy to have these pens working again.

This works as expected, and has surprisingly allowed more flavor to come through in my espresso shots .I only gave 4 stars because the instructions for assembly are not really clear,or maybe I am just dense, the rubber disk goes on top of the needles to help secure when the holder is screwed into the handle. Took me a minute but I did figure it out.I am very happy with how it works!

Ink is great writes smooth.

excellent customer serviceI had a problem with the ink, their customer service responded immediately and solved my problem 100%- I'd buy here again no problem

Terrible quality. I tried every one. They will write if you scribble like your trying to get the ink to flow. Then when you write they skip and don't work. Then you scribble and the ink flows again, then when you write it skips. The quality of the ink is terrible. Some of the refills would not even screw into the pen because they were already stripped.
