Learn-to-write fountain pens - Which is the right one? A help for parents.

[@ichirofakename]

Here is a data point in case someone might find it useful. I have a collection of 12 different beginner pens with nibs from Germany. I like them because I find the nibs very round, sturdy and reliable. Also I am amused by the kiddie aesthetic. I have formed opinions on 7 of them, the other 5 being unremarkable:
RECOMMENDED
Pelikan Pelikano jr - reliable and smooth
Schneider EASYbuddy - nicely wet and extremely smooth.
Lamy Nexx - pleasant.
NOT RECOMMENDED
Faber-Castell Scribolino - leaked, too wet.
Herlitz Tornado - too dry
Lamy ABC - awkward, too dry
Rotring Primus - too fine
Cheers
