The Safehouse Collection is a Valve-made collection of CS:GO skins introduced on 27 November 2013. The collection consists of 5 consumer skins, 6 industrial skins, 3 mil-spec skins, 1 restricted skins, 0 classified skins, and 0 covert skins.
CS:GO skins from the Safehouse collection are commonly used as “filler skins” in trade up contracts from mil-spec to restricted rarity due to the low cost of the skins and the shear abundance of skins available. The SSG 08 Acid Fade is most desirable for trade up contracts because of its average lower float and it only being available in Factory New wear condition.
