How to use Copper Pouches in Crimson Desert

Kliff starts his (second) life in Crimson Desert without much money. You'll have no coin to your name, but plenty of things you'll want to buy, from inventory expansions to weapons, armour, and food. It's also not easy to make money at first. That is, if you don't make use of Copper Pouches.

You'll get these bags often from killing bandits and looting or stealing items more generally, so you'll quickly rack up quite a few of them. But it's not immediately obvious what they even are and what you're supposed to do with them.
