Knifeless sim slab
Every pull is graded like a collectible card: tier, wear, float and pattern sealed on a slab. Classified and rarer pulls get a foil.
Prisma Case
M4A4 | The Emperor and Five-SeveN | Angry Mob are the covert skins of the Prisma Case, and between them they drop on 0.6% of opens.
One step down, the classified tier holds AUG | Momentum, R8 Revolver | Skull Crusher and XM1014 | Incinegator, at 3.2%. At the top of the case sits the rare special tier: Navaja, Stiletto, Talon and Ursus knives, landing on 0.3% of opens. That is a lower figure than the covert pair gets.
The simulator rolls every open at these odds, and each open is drawn on its own, so a run of plain skins says nothing about when a knife comes.

Questions
- What is inside the Prisma Case?
- There are 17 weapon skins from mil-spec to covert, plus the knife tier on top. The restricted tier, which takes 16% of opens, is AWP | Atheris, Desert Eagle | Light Rail, MP5-SD | Gauss, Tec-9 | Bamboozle and UMP-45 | Moonrise. Each of these can also drop in StatTrak form.
- What knife can you get from the Prisma Case?
- The knife pool has 28 finishes. Each of its knife types comes in the same finish list, plus a plain version with no pattern, such as ★ Talon Knife. Examples from the list are ★ Talon Knife | Doppler, ★ Stiletto Knife | Marble Fade, ★ Ursus Knife | Tiger Tooth and ★ Navaja Knife | Damascus Steel.
- What skins are in the Prisma Case?
- The mil-spec skins, which fill 79.9% of opens, are AK-47 | Uncharted, FAMAS | Crypsis, Galil AR | Akoben, MAC-10 | Whitefish, MP7 | Mischief, P250 | Verdigris and P90 | Off World. They sit under the restricted, classified and covert skins, and together these tiers hold every weapon skin in the case.
- What are the odds of getting a knife from the Prisma Case?
- The rare special figure is for the whole tier. Each open picks a tier first and a finish after that, which leaves any one knife, for instance ★ Stiletto Knife | Doppler, with a small fraction of the 0.3%. Plain and patterned knives are drawn from that one tier alike.
- When was the Prisma Case released?
- The Prisma Case came out on March 13, 2019. Its covert pair is M4A4 | The Emperor and Five-SeveN | Angry Mob, and its knife tier includes ★ Talon Knife | Marble Fade, ★ Navaja Knife | Rust Coat and ★ Ursus Knife | Ultraviolet. Lower down, its AWP and AK-47 skins are the restricted AWP | Atheris and the mil-spec AK-47 | Uncharted.
- Is the Prisma Case worth it?
- Check the expected value on this page, which is before fees: the average item value one open yields at these odds, next to the cost of a case and key. ROI and profit chance beside it are read from the same prices, and we leave the call to those figures.
