Every case returns less than it costs — that gap is Valve's margin. Buying the skin you want on the open market is cheaper than unboxing it, every time. See our case opening ROI guide for the full breakdown.

Your odds over multiple opens

A 0.26% knife chance is hard to picture. This is the same number stated the way it is actually experienced — the chance of at least one, over a run of opens.

100 opens costs $593.00 and returns about $404.71 on average — an expected loss of $188.29.

A coin-flip shot at a knife takes 267 opens — about $1.6K at this case's price. Even then it is a coin flip, not a guarantee: the odds never carry over between opens. More in our CS2 case odds guide.

Opening the Spectrum Case

The Spectrum Case costs $3.44 for the container plus a $2.49 key — $5.93 per open. At live market prices it returns $4.05 on average, which is 68c back per dollar — an expected loss of $1.88 every time you open one.

It contains 17 weapon skins and 30 special items — knives or gloves — in the 0.26% gold slot. Reaching an even-odds chance at that gold slot takes about 267 opens, roughly $1.6K at this case's current price. Every skin in the pool is listed above with its live price, and you can open the case as many times as you like here without spending anything.

CS2 Case Drop Rates

Mil-Spec (Blue)79.92%
Restricted (Purple)15.98%
Classified (Pink)3.20%
Covert (Red)0.64%
Knife / Gloves (Gold)0.26%

These odds are the same for every weapon case. They do not improve with streaks and they do not carry over — each open is independent, which is why a run of bad luck never makes the next open more likely to pay.

Already own skins?

Unboxing is the most expensive way to get a skin — the panel above is that arithmetic. Selling what you already have is the other direction, and these marketplaces buy skins outright, grouped by what the money actually is, because the two kinds are not comparable.

Pays cashMoney out, to a payment method you choose.
Pays site creditBalance on that site, to spend there. It usually reads higher than a cash offer for the same skin, which is why the two are not ranked against each other.

What any of them pays depends on the item. Open a skin's page — every item in the grid above links to its own — for that skin's live payouts.
