The Spectrum Collection is the weapon collection of the Spectrum Case, added to the game in 2017. It holds 17 weapon skins, from Mil-Spec Grade to Covert. SkinsMonkey lists every Spectrum Collection skin with prices for each wear level.
The Spectrum Collection is the set of 17 weapon skins tied to the Spectrum Case. Every skin in the set shows The Spectrum Collection in its in-game details. The case also drops 5 knife models as rare special items: Bowie Knife, Butterfly Knife, Falchion Knife, Huntsman Knife and Shadow Daggers. Knives are not part of any collection, so you will not find them in the list below.
A trade-up contract takes 10 skins of the same rarity and returns one skin of the next rarity up, picked from the collections of the skins you put in. Fill the contract only with Spectrum Collection skins and the result is always a skin from this set. StatTrak and regular skins cannot be mixed in one contract. Since the CS2 update of 22 October 2025, five Covert skins can also be exchanged for a knife from the collection of one of the skins used. With five Covert skins from The Spectrum Collection, the knife comes from the Spectrum Case pool.
The Spectrum Case page covers the container itself, and all CS2 collections are listed on one page.
