Pelikan M600 Pink with fine nib. What could be more springy than the Pink Pelikan? Probably only filling the Pink Pelikan with pink ink. Now that’s turning spring up to 11.
I think Diamine Carnation is a perfect spring pink.
The pen is really a raspberry sort of pink. But not an actual raspberry: it’s like a raspberry pink dye. Raspberry-colored shiny plastic product. Raspberry-flavored hard candy.
And let’s not forget the Pink Pelikan comes in the Box of Bad Taste.
So I think the Pink Pelikan goes to 11 all by itself, really.
