These labels are accurate. They were redrawn and vectorized by ~Donpedro1337. Juggernaut Soda, REVIVE Soda, and Sleight of Hand Soda are the correct labels. If you need further proof, there is a display case in the starting room of Kino Der Toten that contains the four original (but unusable) perks inside.
!! DO NOT comment with corrections !! These labels match the original ones in game as close as possible! Thank you.
I also still need to add the white sombrero to the top of the Mule Kick bottle, so that one isn't exactly complete yet.
Other than this, thank you all so much for all the comments and favorites. It means a lot that you take interest in my work.
Real legitimate replicas of the Perk-A-Cola's from Nazi Zombies. Made from real drinks, these Perk-A-Cola replicas are the closest to the in-game models as possible. If only they actually worked!
