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

Unbelievable QUALITY ! Smoother than original rotring gel. Fits my Rotring 600 perfectly !!!!

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.

The new pen doesn't write

2-3 of the refills don't fit properly so the bolt action will not work. Also I write the same amount every day. Some of the ink refills will last half a day. Some a couple of days. Some 2 weeks. Unfortunately there is only about one of those per pack. I bad the refills aren't as good as the pen.

My pen had been run through the washer, so the original refill was destroyed. I needed new ones and these arrived fast. They also work perfectly.

The gel inserts write very well, and are nice and smooth. However, they seem to run out of ink very quickly, and with metal casing, it’s impossible to tell what the ink level is as you go or if you are running out. Additionally, it seems to suffer from frequent difficulty in starting in flow, or even pausing and catching during writing. Overall, could definitely benefit from a redesign.

Commande reçue rapidement et aucun problème sur les recharges.

Pen refills had flow problems, one out of the batch worked correctly ended up buying Parker pen refills the ink flow is more consistent

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

Sorry but the gel refills are terrible. The flow is inconsistent and will not last as long as even a cheap disposable gel pen. Considering the pens are robust and high quality pens, I am disappointed that they have produced some of the most unsatisfactory refills I have ever come across. Avoid.

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.
