I recommend getting the app Fable or Goodreads (fable is better imo). It’s like social media for reading and will give you recommendations and u can see what your friends are reading if you follow people

I like the aluminum ones too but the weight of the brass makes that version my favorite Kaweco sport! Either one is incredibly durable! I want to get more

Also, small world! I bought my Retro 51 long-knife nib brass fountain pen from Goldspot about a year ago and it’s one of my favorites!

I like the aged look too!
