Black Gel Ink Refill Bolt Action Pens, 0.55mm Fine-Point Tip, Deeply Pigmented Black Gel Replacement Cartridge in Metal Casing, Gel 6-Pack

Exactly what I needed, as advertised, on time, and quality refills. Ink is wet and dark. Recommended.

Writes and works well immediately. Time will tell.

I picked up the BASTION Premium Pen Refill to keep my writing instruments performing at their best, and it's been a solid choice. The deeply pigmented ink flows smoothly, providing a consistent line without any skips or smudges. Whether I'm jotting down notes or signing documents, the writing experience feels effortless and precise.​ The refill fits perfectly into my pens, and the build quality is evident—it's clear that this is a well-crafted product designed for reliability. The ink dries quickly, which is a bonus for someone like me who tends to write quickly and doesn't want to worry about smearing.​ Overall, this refill has met my expectations, delivering a dependable and enjoyable writing experience.​

Get the gel, for some reason the other ones only half way work. The gel work very nicely though.

Great refill!

Poor quality cartridges that write very inconsistently. Returns was annoying.

I absolutely love this brand have loved everything I have received from them whether it be from amazon or their website. But when I ordered these gel refills I was hoping for that nice, dark gel look and feel but got what felt like an old or dying cart instead. I tried each one of them over the course of a few days and could get them to write well on some paper but not in any of my journals. I feel like I prob just got unlucky with the batch or maybe gel just isn't what I should be using because I ordered the blue ball point refills and they work and feel amazing. Def shouldn't be looked at as a reflection of the company our its products but just wanted to share that my experience and see if anyone else agrees that I may have had a bad batch or if gel just isn't right for me. Bastion I love you! Keep making good products and ill keep coming back for more.

Yes they were a direct replacement

I was recommended this type of refil by a friend and when it works it is really nice and smooth but the problem is it's seems to take a long time to get the ink running smoothly (I've scribbled constantly to get the ink to flow) and even after a while of use it just keeps on stopping and out of frustration I have stopped using them and gone back to the traditional standard bastion refils. I may have been unluck but I'm not buying them again.

Bought the Gel based ink refills, ok but found them quite scratchy, certainly not as smooth as the standard ink refills.
