Predator skins feature a brown-green jungle camo pattern with a spray-painted finish. The Predator skins family currently has three members which were all added to the game in different updates at different points in time. Since they all belong to different collections, Predator Skins can only be acquired by opening various csgo weapon cases. Skins of this family can be in all five exteriors and some can feature Souvenir stickers.
In terms of value, prices range from just a few cents to up to $40. The value depends on the weapon itself, the skin exterior and whether it's a Souvenir Predator skin or not.
