## Questions & Answers

**Q: Is the ink waterproof?**
A: It seemed to do okay in a normal rain. Having to write different reports on aircraft out on the flight line. I wouldn't say waterproof but it got the job done. I don't do much writing in the rain but the comfort of this one with my arthritic hands is second to none. Highly recommend. I would suggest you grab a few refill cartridges they're inexpensive. I get a couple months out of one. Enjoy the pen, I've got 2.

**Q: Will these fit the Bastion mini Bolt Action... it says "all"?**
A: all standard size pens; it will not fit our mini.  Use ASIN: B0B4T4R2FY for our mini version

**Q: what is the length of this refill?**
A: It looks similar to a Parker G2 refill. Length should be 98 mm.

**Q: Are the Bastion refill ink cartridges refillable ?**
A: Ballpoint pen refills work exclusively with our Bastion Bolt-Action Pens. We do not research or maintain lists of brands that may or may not work with our pens. We only guarantee our refills with our pens. Use of any other brand voids warranty should an issue occur.

We expressly inform people to purchase our ink cartridges exclusively for our pens. Not all of our pens have the exact same internal dimensions.  The fact that another brand fits a particular pen style is a coincidence.
