Two good looknmg pens Alex.
Honest feedback?....
I like the profile you've put on them. I see a lot of very fat looking slimlines, which whilst they demonstrate the use of tools and finishing techniques, are not necessarily very comfortable to write with. Yours are more slender and therefore look not only more comfortable, but also more pleasing to the eye.
Your second pen appears as though it needs the refill to protrude a shade more. That's easily overcome with a slimline, as you just need to press the mechanism in a tiny bit more, and that will solve the problem.
