Keychains arrived in CS2 with the Armory update. Valve’s notes call them charms, the game files and many sites call them keychains, and both words mean the same small object hanging off your gun. They are cosmetic, they are tradeable, and they confuse people who try to price a skin with one attached. Here is how they work.
What a keychain is
A keychain is its own item in your inventory, like a sticker or a patch. It has a name, a rarity color and a small 3D model: a miniature weapon, an animal, a piece of food, a joke. It does nothing until you attach it to a gun. Once attached, it hangs from the weapon and swings as you move, reload and inspect.
Charms come in collections. The first two shipped with the Armory. A collection is a fixed list of charms across rarity tiers, the same way a sticker capsule is a fixed list of stickers. If you want one particular charm, the market is the place, and it costs whatever that charm’s supply and popularity have settled at.
How it attaches
- Open your inventory, select the keychain, and choose the weapon skin you want it on.
- The game shows the weapon with the charm hanging from it and lets you choose where it hangs.
- Confirm. The charm is now part of that weapon’s item and travels with it if you trade the gun.
One charm per weapon. The charm follows the skin, not the loadout slot, so if you swap to a different AK-47 skin, the charm stays on the old one.
It comes off again
This is the part that separates charms from stickers. A sticker scraped off a gun is destroyed. A keychain removed from a gun goes back into your inventory as the same item, ready to hang on something else. You can move one charm between guns as often as you like.
That single fact drives everything about how charms price.
The pattern number
Inspect a charm and you will see a pattern number alongside the name. It is assigned when the charm is created and it does not change the look. Two copies of the same charm with different numbers are visually identical. Some collectors chase particular numbers on the same logic that makes people pay for a very low float. It is a hobby inside the hobby, and the market for it is thin.
Does a charm change the skin’s price
Usually no, or very little. Three reasons.
- The charm can be removed. Anyone selling a gun with a valuable charm on it takes the charm off first and sells it separately. So a charm you find still attached is, in most cases, one that was not worth the effort.
- The market does not see it. On the Steam Community Market a skin with a charm is listed under the same item name as a skin without one. Buyers sort by price, not by attachments. The charm rides along and does not push the price of that listing up.
- Taste is personal. A charm that suits a skin for you is clutter to the next buyer. There is no agreed idea of a good charm on a given gun the way there is for a matching sticker craft.
The exception is the same one that exists for stickers. A rare charm on a gun is worth roughly what the charm sells for on its own, because the buyer can take it off and sell it. So treat it as two items: the skin at its normal price, plus the charm at its normal price. If the seller is asking more than that sum, the charm is being used to pad the number.
| Attachment | Removable | Effect on skin price |
|---|---|---|
| Sticker | No, scraping destroys it | Small unless the craft is well known or the stickers are rare |
| Keychain | Yes, returns to inventory | Close to the charm’s own value, no premium for the combination |
What to check when buying
- Price the skin as if the charm were not there. Float, pattern, exterior. The charm changes none of them.
- Look the charm up on its own. If it is worth something, fine, you can keep it or sell it. If it is a common one, it is decoration.
- Do not pay a premium for the pair. There is no craft value in a charm the way there can be in a sticker set.
On PrefireSkins the listing tells you the exterior and, where the inspect data provides it, the float. A charm, if one is attached, is visible in the inspect image. It is a bonus, not a reason.
What charms are good for
They are good for exactly what they look like: a bit of personality on a gun you already like. Put one on the skin you use most, pick the one that makes you smile, and move it when you change skins. That is the whole use case. It costs the price of the charm and nothing more.
The skin sets the price. The charm is a passenger, and it can get off at any stop.
