Refinement Tokens are a new currency added in Crimson Desert's packed 1.01 update. You'll most likely have seen the pop-up window letting you know you've got some Hernand Refinement Tokens, but you're not explicitly told what they are. However, the clue's in the name: they're a new item used in refining gear, and they're a real time-saver so you don't want to forget about them.
There are also Refinement Tokens for other regions, such as Pailune or Delesyia, but you need to progress further to unlock and use these so you might not have them yet. Below, I'll explain what Refinement Tokens are, how to use them, and how to get some more of them when you run out.
