It’s specifically for their Polaris and Nebula finishes. They’re pretty unique. I ordered both last night anyway. I am not expecting a huge amount but as long as they’re decent writers I’ll be happy. I mean surely they’ll be as good as a Pilot Prera or Lamy Vista both of which I enjoy as every day writers and don’t need to worry about hurting unlike my Lamy 2000 lol Had quite a few positive reports from Fountain Pens Oceania faceballs group too though.
