@redbird The Kakimori is fantastic. If you’d prefer a more pen-like experience try the Sailor Hocoro (https://www.afth.co.uk/sailor---hocoro---dip-pens-1333-c.asp) which you can get in a couple different nib sizes & colours, as well as a feed so that it holds more ink per dip.
I feel like “ink per dip” or “ipd” should be a unit of measurement we use for dip pens 🤣
@kalanggam As others have said, the Hobonichi's are great with fountain pens, or if it's more of a pure journal you're after the Luechtturm1917 Bullet Journal performs excellently.
