Cool to see another fountain pen enthusiast here! :)
I also collect fountain pens and inks. I'm fairly particular about them in terms of appearance and how they feel to write with. I also like to try out pens from different countries--China, India, Taiwan, Japan. I still need to get a European pen or two for my collection; I've been eyeing a Lamy for a while now. I have a couple particular inks I'm considering getting, though I still have a ton of ink to work through as it is.
Besides that, I also collect manga by Osamu Tezuka and lucky cats (though only from places I've visited on travels).
another taxidermy collector, nice! :D any specific animals you gravitate to, or more of an anything-goes type of thing? (I for one wish possums were a lot easier to find, you can only really get deer and the occasional fox around here if you aren't shelling out hundreds of dollars :c )

Oh yeah, I used to collect (sealed) glass jars with dried flowers and potpourri in them because i thought they were really pretty, plus fun to mix in when decorating with skulls/bones, but every time my mom (and permanent roommate) even saw the slightest hint of one she'd constantly berate me about how her grandma used to have a bowl in her bathroom in the 80s and go on and on about how it reminded her of her grandma's bathroom and bathroom bathroom im gonna say bathroom a few more times to make you (me) uncomfortable and ashamed for liking (let alone collecting) the pops of color in my autistic depressed ass life. so uh, yeah i dont have any of it (even just the plain dried flowers) anymore...

I collect funny license plates :- ) by that, i mean i/my friends take pics when we see em out in the wild! I have over 50 atm and still going! I also collect lamb plushies
Oh man, I have such a collector habit, it’s really bad lol I collect hockey pucks, Funko pops, autographs, Zoids model kits, NHL trading cards, Jellycat soft toys, hockey jerseys. Those are my main current ones lol

I like to collect little animal incense holders :3
I collect cute keychains and anime figures! I love collecting, though, so I feel like I have many little collections like Pokemon cards, stickers, etc. But anime figures and keychains are the two collections I actually focus on!
I collect toys mainly, I'm obsessed with Monster high dolls and other fashion dolls that I find unique, I also collect pokemon cards. As far as toys go anything really cute like MLP, Littlest petshops, interactive pet toys. I love plushies and build a bears, I'm a child I have a whole toy room for my collection.
weird/pretty bottles and cups... feather pens, snowglobes and anything with dinosaurs or cats. i wanted to collect ball jointed dolls but i only had enough money for one cause they're so expensive lol. if i had enough money id totally collect antique dolls.
I collect merch (plushies, figures, keychains, etc.) of my favorite Monster Hunter monster, Barioth, as well as figures and various items for my favorite anime, Madoka Magica. But my biggest collection is probably teddy bears- I have such a weakness for them; I have to stop myself from buying every cute bear-themed item I see because I know I’ll run out of room. ;u;
Oh boy loaded question.... well I collect books, video games, anime/comic figures, pop figures mainly...
I collect vintage playboy/hustler magazines and LIFE magazines. I need a better way to store them but they are so interesting to read. The LIFE ones especially since in the 40's every ad says BUY WAR BONDS and it's surreal.
I also am collecting anything deep red. I'm making a wall in my office be monochromatic with deep reds.

Bit of a morbid one but snake wet specimen jars (that I make my self, ethical natural death only). Also build a bears.
My Little Ponies (the ones from the 80s) and ball-jointed dolls.
I collect crystals/gems/minerals
Uranium glass! I’m getting a roll of black lights this Christmas so my entire curio cabinet will glow bright green. Also, Beanie Babies, but I put that collection on hold because of the pandemic. I won’t be browsing garage sales again any time soon :/

I have a few collections. My biggest collections are my comic books, and my tabletop RPG books and dice. I collect books for Dungeons and Dragons (various editions), World of Darkness books (Vampire, Werewolves, Mage), Robotech, Pathfinder, Shadowrun, and then also books from other gaming systems that make good reference for the world that my husband and I have created for use in Pathfinder. I also have an extensive DVD and book collection.
