For lefties out there: Lamy has a lefty-based nib. If you're curious picking up a Safari might be life changing. It's so much smoother than a ballpoint. I accept smudging as a way of life though
Source: grew up somewhere where children write with fountain pens at school. I don't remember smudging being a huge issue but it has been a while as well.
It's always interesting seeing Lamys being sold as the high end writing experience in one country and the standard pen for kids in another. Not that there is anything wrong with that. Both are equically true I guess :)
IIRC works via a reaction with cellulose in the paper or something.
