As the title suggests, these are a must-have for the 1st edition, simply because there are not enough german markers to even mark every territory you own from the beginning of the game! You could of course just leave out the core territories, arguing that it's obvious they belong to you - but in later complicated war situations it might get messy. Just get some more of these and conquer the whole board, goddamnit! :) (They do not fit entirely with the 1st edition markers, being 1mm bigger and having a slight texture on the cardboard, but this could really only be important for collectors)
