- Black Ballpoint Refill Bolt Action Pens, 0.55mm Medium-Point Tip, Standard Black Ink Replacement Cartridge in Metal Casing, Black Ballpoint Single Refill

This refill works perfectly if you have a bolt action pen. I made the mistake of using the ballpoint refills but they don't work as well with bolt action.

Writes well, and fits my Rotring Rapid Pro. Definitely worth the price.

There’s so much research on the refill pin I needed. This was the one was perfect. It writes really well and the description was very helpful.

I got a great pen and needed this refill. The writing is thicker than I thought it would be. Color is a good shade of blue not the bright blue shown.

The titanium is light but sturdy. Its fidget friendly and writes smooth. Great pen for the price

On time delivery and the refills fit my executive pen. So glad I will not have to send back. Thanks Amazon

Bought when I got bastion pen. Pen nice refills not so much. Both lasted about a month. Just purchased off name brand 6 for the price of these two. Writes better will see how long they last.

Good quality, performed as expected

Excellent service. Items arrived promptly and were exactly what I required.

Love me a good Caran d'Ache pen. My dad buys the limited editions pens throughout the year and gifts them to family. I have several of them and needed black ink for work (rather than the blue they come with). No scratching or smudging. Comfortable writing.

The Bastion brand is very strong and reliable. These refills are perfectly matched with the pens. I use my Bastion pen every week, I have dropped it many times, it just keeps going! Always reliable, smooth writing, goos value for money!
