CS2 UMP-45 skins
All 45 UMP-45 finishes in CS2. Open one to see it in 3D, try sticker crafts on it and check the cost of every part.
UMP-45 sticker crafts
Every UMP-45 skin takes stickers on its right side, the side CS2 shows when you inspect it. Pick a finish above, place stickers in its slots, and copy the craft into the game as a gen command or an inspect link. Skins with starter crafts open with one already placed.
