WTB - Random items for a beginner in the hobby!

As suggested by the title, I'm completely new to this hobby. I've recently purchased three Pilot Kakunos in EF, F, and M and several notebooks.

I realize how vast this hobby is and instead of purchasing a bunch of items one by one I figured there may be some people who have some items they'd be willing to sell to help me out? Various fountain pens, various size nibs, various fill types, inks, and anything else you can think of. I’d love to buy a few lots from people to really immerse myself in this hobby and figure out what I like!

Thank you in advance! 😁

I did message the mods prior to making this post to ask for permission as I’m a long-time lurker through google searches, but I’m a new poster who was recommended to this group from another.
