What's inside the CS20 Case

Is the CS20 Case worth opening?

One opening costs €2.80 (€0.55 for the case and €2.25 for the key) and returns €1.18 on average. That means you get back about 42% of your money and lose about €1.62 on every case. On value for money, the CS20 Case ranks 31 of 42 cases.

Most of the value sits in the rare drops: 25% of the expected value comes from the Classic Knife, which drop once every 385 cases, and 20% from the Covert skins. Almost 80% of openings give you a Mil-Spec skin worth about €0.40.

The value uses buy prices. If you sell what you unbox you get less: Steam keeps 15% of the price and the money stays in your Steam Wallet. If you want a particular skin, buy it directly; it is almost always cheaper than trying to unbox it.

Opening cases is gambling. Only open them for fun, and only with money you can afford to lose. Guide: are CS2 cases worth opening?
