Full transparency I purchased this pen for the option of the changeable ink refills which is great as I prefer a fine blue refill - Parker.
The Pen itself is very well made and looks good with the titanium clip. The Bolt Action works seamlessly. Writes well for medium black and has good weight.
Subjective - for me (a woman with smaller hands), I find the circumference of the Base Line Bolt Action Pen just a little to much for me to write with it on a daily bases hours at a time, as my fingers tire. But I have 3 Mini dual side click's, (Copper, Brass and Titanium-Raw), pens which are perfect for me. I use these Mini's Copper and Brass daily, and the the Titanium-Raw and the Base Line Bolt Action Pen- Copper are in my purse and are used as needed when I am out and about. I have adjusted to blue medium refills for the the mini's. Still looking for "fine blue" refills.
Notwithstanding, I would still recommend this pen.
Thank you,
Sincerely,
CS
