L: 2.75inch 7cm 70mm,0.7mm Tip, Liquid Ballpoint Pen Refills Compatible with Crystal Pen and Screwdriver Pen, German Ink，Suitable for Liquid Sand Pen,Tool Pen (Blue 6PCS)

It does what it is supposed to do.

I used this ink refill in my crystal swarovski pen and it gave it new life! It fit in the pen perfectly and writes well.

I needed to replace the ink in a small, bullet pen. I wasn't sure if these would be the right fit, but they were. The tops can come off, so depending on your previous ink, you can take the top off and use the the top from your original ink to make it fit. They write great.

Wish product fetails included description of NOT MADE FOR CLICK PEN. Worth the price if I had pens for it to fit.

Fit great and write great

Sadly, we ordered refills hoping to save some plastic (the pens) going in the landfill. Sadly, we ended up just wasting packaging material, time and fuel to get them here - and now back.Fit perfectly in the pens, but they write for about three times - then nothing. Have tried four of them, all the same result. MAYBE I got a bad batch - but not worth trying another to find out, and I recommend you don't either.It's a shame.

I had some really nice Twist to Open pens that ran dry., these work great

These are running out of ink way too swiftly.

Ink seems to be dry very dry, measurements are off to. To small for the p3ns I ordered them for
