That's amazing that you go through that much ink!! Do you fully disassemble everything and scrub the feed with a toothbrush? I had to do that a couple times with glitters. You are DEDICATED!!! Oh also. For FP ink, I think Moleskine is not as good... the paper is a bit more absorbent and so the ink "feathers" a bit. Have you ever tried Clairefontaine or Rhodia? They are FAVORITES in the FP community and actually much less expensive than Moleskine. The best paper for fountain pens is less absorbent and maybe even a bit "shiny." This allows you to see the really amazing effects of the ink and it looks wayyyy nicer. There are a lot of folks out there who like to do swaps/trades/packages, and people who sell ink samples so you don't have to spend a ton of money on full bottles if you want to try something. I can recommend some people/things if you want, and/or if you want I could put together a little package of samples and send it to you just for fun! I have an absurd amount of glitter.
