Well, I have become addicted to fountain pens.  They write much nicer than ball point pens.  So far I’ve been buying them from Massdrop.

I have the an OHTO Rook (they no longer have a Rook FP on the site, looks the same as what I linked) and an OHTO Tasche.  I had two OHTO Dudes on order right now, one blue and one silver.  Ended up reading some bad reviews on them and now I have two Fountain Pen Revolution Indus on order instead.
