I keep my journal in an A5 waterproof paper traveler's notebook/fauxdori style cover. Inside are two notebooks, my journal, a self-made felt pocket-thing, and a traveler's notebook size plastic zip folder which can hold some pens/etc if I wanna take extra s t u f f.
During 2000s - 2010s most of my journalling was online and public. Sadly they're all long gone but I have fond memories of Diaryland, uJournal, GreatestJournal, and like 300 other Livejournal clones (I had an LJ too but I just lurked fanficrants). I don't journal online anymore and doubt I would go back to it again, though I miss the old blogging sites and the fanatical obsession with using the perfect 100x100 icons.
Fountain pens are forever my baby. I use a blossom red TWSBI Eco with extra fine nib. At the moment it's filled with Diamine Eclipse, a dark grey-toned purple ink. Or blue-black. To me it looks more purple.
I have used classic Lamy Safaris but the triangular grip is uncomfortable :( My dream pen right now is the Sailor Shikiori Dragon Palace.
+ pen and inks
