I printed out Mekon's awesome counters for my first copy of the game and have been storing them in snack bags. It was driving me crazy always searching for the right counter when setting up scenarios. I would dump the bag out and pick through them. It was tedious.
While visiting my local Dollar Tree I came across these 7-Day Pill Organizers with 14 compartments:

Here they are closed. I'm not putting stickers on them yet but will to identify each compartment.
So for $3.22 I have all my counters organized. I will be buying more for Mekon's other sets.
