Our ink cartridges are fine tip and come in the following colors and ink types:
  • Standard ink - Black, Blue, Red
  • Gel ink - Black, Blue, Red
Our cartridge description is expressed as a particular type of Parker refill, which is the G2 ISO 98mm length, 5.8mm width, fine tip (.05 mm) version.  
The shape must match the original version shown in our product image.
Parker is changing the style on some that they still describe as G2 ISO with a wider body that continues all the way down virtually to the point.
Our pens require the 'classic' G2 style with the tapered end toward the point.

Always great products and service

new pen owner
very helpful customer service

I had 2 orders placed, one for a pen and one for ink, that wouldn't ship to the same address. Without being promoted they emailed me and asked to clarify/verify shipping. Great customer service and a badass pen to top it off with! But I do wish the new pens had an option for blue ink. Oh well.

Awesome Pens!!!

I purchased my first Bastion gear pen a month ago and immediately, this pen jumped to the top of my EDC pens. I use them every day for notes at home and for work. These pens are comfortable and durable. The ink that comes with them works well in room temperature weather, but I have not yet used it in cold temperatures. Oh and I now have three Bastion pens (aluminum, titanium and stainless).

Better Blue

I received a Bastion Stainless Steel Bolt action pen for Father’s Day. I prefer blue ink and these replacements were perfect for my style of use, which mostly writing notes in my Field Book. Easy to change out too.
