My spouse’s Hongdian Black Forest has a very satisfying cap. I’ve sat there uncapping and capping over and over just cause it feels so nice lol. I don’t normally like really hard nibs but it writes so nice I secretly covet it. Its also been super reliable.
If you don’t mind second hand (since they’re not made anymore), a Pelikan Level has the most enjoyable closing cap I’ve ever experienced. Albeit It’s a sightly unusual but unique looking pen.
Thanks for the heads up cmdr o7
