CraftMates storage binders are an excellent choice for storing your wargaming counters! Made for beading, they can be found at retailers of craft supplies.
Two snap tabs secure your counters for safe travel. Inside, you'll find a clear flap on each interior side; the right side holds four bar trays with individual storage bay cells, that have a nice rounded front and back bottom in each cell. The lids of each cell pop up when you depress a switch at the far left side of the bar unit. These are excellent when just using certain counters, or divvying up to each players' sides. The left side clear flap can be used to hold notes or small charts.
These are fairly inexpensive and an excellent tool in your arsenal!
"Every day when I wake up I don't let the old man in. My secret has been the same since 1959-staying busy. I never let the old man into the house." — Clint Eastwood
