Zombicide survivor/zombivor card holder

This is a survivor/zombivor card holder for zombicide season 1 (may work with other seasons).
It prevents the 5 cards to move every time you need to add 1 XP. It happens to me all the time and it's sometime hard to replace the cards as they were before they get dropped.
2 versions :
- The double one covers both side (survivor/zombivor) at the same time.
-The single one covers only one side, two singles can be used at the same time (it's the double one splitted in two parts).
