Cosmetic Items are items that players can buy with Nether Gold, or large amounts of cash, that the player can use to outfit their character. Cosmetics and gold unlock keys are the only items that will stay in your inventory, even after death. They can also be found by unlocking gold containers around the map. The most common gold container is a car.
This is a work in progress, so please list all the different types of head cosmetics and arm cosmetics you can below. I'll organize them into a list later.
