Schneider103901 GS Cartridge Gelion 39 Black

I've tried a bunch of refills but these Gelion are by far my favorite

The product came well-packed, in an A5 bubble wrap envelop. I love how the Gelions write. They are a little hard to find in my country, but my purchase experience from the seller (through Amazon) was smooth and easy to navigate. Thank you!

Works beautifully

When they're not skipping on every other stroke the refill has a noticeably scratchy "feedback" feeling. If you used say an energel or uni-ball in a .7 you'll be disappointed both by the lack of smoothness as well as an ink that lacks vibrancy. It iss more grey than it is black.This could very well be the best gel style Parker G2 refill given the limited options but if you're hoping for something to equal a Japanese gel refill don't bother and honestly skip the entire form factor.

Used to be using Gelion 39 in my NTP31, till I decided to buy a second NTP31 where it changed to using Gelion+ instead. While using my NTP31 (Gelion 39) and the new NTP31 (Gelion+) side by side, I found that every Gelion 39 refill I use, 10/10 times it gives me consistent nice ink till it finishes. Gelion+ however seems to dry out fast, even when barely used. There were even 4 out of the 10 refills in this pack so far that was giving inconsistent ink (dried) right after I removed the seal thing on the tip. Felt like as if I am using those cheap ball-point pens that costs a dollar for a huge box. I am not sure if this was due to a bad batch or simply lowered standards.
