Addictive pen to write with. I typically use a fine nib from brands like TWSBI and Lamy. I figured I would end up with a medium nib in this pens but, after a very helpful and profoundly informative purchasing process, I ended up with a fine in this pen. As a left-handed, side-writer, I found it to be a bit dry at first. Most of my lettering is upstrokes, and this pen didn't want to give me much ink to work with on those movements. But the feel of the pen and the nib on the paper was so addictive, I couldn't stop using the pen, writing with it, playing the lettering and spacing. I quickly went through nearly two fills of the included con-70 (and the associated washes and soaks) and that's when the pen really started to perform for me. The ink flowed brilliantly and brought out the best in my handwriting.The whole pen feels incredible, very well put together, and the performance is outstanding. From a possible regret to a daily workhorse! Wonder Pens, as always has incredible staff who are so attentive and helpful. The service is second to none. Thank you!
