Bolt Action Mini and Side Click Mini
The Bolt Action Mini comes with a Pilot G2 mini.
The Pilot G2 Mini is about 0.7” shorter than the Parker style refills and is still about 0.2" too short for the Fisher Space Pen refill without the adapter on the back. It’s a weird oddball of a refill and about the only thing we have found that works is getting a 3D printed adapter that allows you to use D1 refills:
One day we will get a 3D printer and start offering these from our website, but for now you can get one from the link above. There are a few good D1 refills, but my favorite is the Jetstream version you can find here:
