I just got a Commodore's Credential and it's terrific! I got a medium cursive stub, the first time I've had one, and it's delightfully smooth, yet somehow characterful. Seems wettish, which is what I like, with just the faintest hint of feedback, which for me makes it more pleasurable to write with, rather than less.
I treated myself to this pen for my birthday, and I really didn't expect it to arrive in time, today. But it did, even though I only ordered yesterday afternoon. It's a little bit of luxury at a really very modest price.
Thank you, Mr Pen!
Thank you for the very nice comments. I too have been writing with this pen for some time. The nib is one we have not used before and it is really smooth and wet.
