SchneiderGelion+ Gel Ink Cartridges, 0.7 mm, ISO Format G2, Black Ink, Box of 10 Refills (103901)

Schneider Gelion+ Gel Ink Cartridges, 0.7 mm, refills work as well as the original cartilage supplied in the pen itself. I personally prefer the Gel, it does not skip when certain paper/s are used. Also when paper has been handled too much and leaves oil from skin & finger tips, whick again causes skipping.

These refills are smooth writing and leave a dark easy-to-read line. They fit in all of my pens that use a Parker-style refill. I will be buying them again when I need refills.

Write smoothly and produces nice, solid black lines. Ink dries faster than a G2.Ive had issues with keeping the ink flowing on my first cartridge, but I’m almost through my second with no issues whatsoever.

Very disappointing. Every single refill was dried up and did nothing but scratch the page. Reviews I've read online said that Schneider had QC problems but that when the Gelion+ worked it worked wonderfully. I should have heeded the cautions. Shame on me, I suppose.Insult to injury, these refills have a diameter of 2.54mm, which is not ISO G2 compliant. That's something that another Amazon reviewer pointed out and that I should have noticed. For a pen made to proper tolerances, they simply won't fit through the tip opening. In the process of failing spec, the shoddy construction is revealed as the metal tip that's poorly press fit onto a plastic end shaft simply pops off with minimal resistance.Do yourself a favor and get a Schmidt easyFLOW 9000, Parker PR4, or Uni Jetstream SXR-600. At least the Schmidt exhibits typical German quality.

Out of the ten count box, nine survived the rigors of international shipping.A paperboard box in a paper board envelope proved to be inadequate protection.The surviving nine refills will be put to good use, the damaged refill did not leak which speaks volumes about the quality of the materials and manufacturing of the product.

This is my refill of choice. The black gel ink is truly black in color, not the charcoal-black color one often encounters with other brands. Schneider Gelion+ offers an exceptionally smooth writing experience and it dries very quickly. Long shelf life too! Highly recommended.

Excellent product, I use a titanium pen that these go with, daily.

Very nice BLUE ink refills, writes very smoothly and has a nice real blue color.
