What a great thread. I had searched literally hundreds or thousands of pens without a really perfect match, when out of nowhere... Marlen Liberty of Art Nouveau series, in green! https://chatterleyluxuries.com/wp-content/uploads/2013/06/IMG_8363-001-copy.jpg This pen is weird looking, bulky and unergonomic, harsh and rough and has strange engravings those i don't understand... and i love it! It could touch my heart without fulfilling every rational aspects. I barely knew anymore i have a heart, that's why this is so very special and could be worth buying. Well it's also distinctive, exotic and rare, piston filler, threaded cap and two tone nib, it's rich in colors, it just has so much character you know... So there's also lot of good in it to make some sense.
But as i started to seriously think about how to get one when only less than 100 pens are ever made, i finally felt that this would never become my primary weapon because of all the unergonomy. I even made similar shape from wood to feel it in my hand but i hesitate way too much. Maybe it fits for tripod grippers but unfortunately i'm not one of them, and i also really want to post my pens.
I also like very much Marlen XXI
but that's too short and i doubt the posting option. Aurora Optima in green auroloide is also on my top list. If it was dimensioned as Aurora 88, i would go and buy it. Maybe i buy it anyway some day. With that much money for a pen, i tend to seek absolute perfection though.
