Several commenters congratulated me for an honest review that didn't sugar-coat my view of the product. I have two things to say in response.
First, to the extent I did not like the writing experience, I chalk it up to getting the odd bad pen. I love the Preppies I own, which appear to have identical nibs, so I don't know why the Plaisir wrote so much squeakier.
Second, if you like honest reviews, stick around. I've got a bone or two to pick with Pelikan: Newbie pen and paper blogger takes on revered German pen maker. Film at 11!
Thanks to all who entered. Don't be strangers!
