1 / the use of the fountain pen is not suitable for the paper who drinks ink by making it reappear at the back of the page. The use is therefore to be reserved for little wet inks.
2 / line spacing is too narrow, which cup the text and make its uncomfortable replay.
The same book but with a lined paper quality or Clairefontaine Paperblanks would have been perfect. It's a shame that Moleskine neglected fountain pens users.
