So I love Lamyminen! I kontiere regularly in my accounting with red mine, it's me not matter what kind of a pen I use. And since cutting a Lamykugelschreiber with appropriate Mine - times B times M - for me at the price / performance ratio still came out on top. I have also had good already cheaper coolies - only the latest when refilling with a new giant refill the results were then from time to time very negative.
