Green:
– Master crafted.
Example:

* Vault crates are not tradable or marketable.

** Precious items are rare. However, if they’re from the dosh vault crates or the dosh vault that gives you a crate, they’re untradeable and unmarketable and actually quite uncommon to find them. If you got it from the drop system it’s a bug (should be tradeable/marketable). If you got it from the USB or crates then it’s very rare and expensive.

*** Cyan blue: crates and USBs.

come in 6 tiers of rarity (Common, Uncommon, Rare, Exceptional, Master Crafted, and Precious) and 3 levels of wear from Mint to Battle-Scarred.

Cosmetic items and weapons skins come in 6 grades of rarity: Common, Uncommon, Rare, Exceptional, Master Crafted, and Precious.
Weapon skins are further modified by their wear condition: Mint, Field-Tested, and Battle Scarred. Free item drops earned in game will be cosmetic items and weapons skins that are one of the first 5 grades of rarity.
The 6th rarity grade is only available by opening a Horzine Supply Crate or an Encrypted Weapon Skin USB.

You can trade items you find during gameplay, obtain by opening a Horzine Supply Crate (wearable cosmetic accessories), or get by decrypting a USB stick (weapon skin blueprints).
