A friend I game with turned me on to these containers from KFC. These reusable containers come with select side items such as beans and mac & cheese. They're absolutely perfect for storing game components such as coins and tokens.
I went to KFC for lunch expecting to get 1 or 2 with my meal, but I came home with 80 of them!
Pros of KFC sealable containers:
-They're compact. They should fit in just about every game box without an insert. -Just the right size for most game components. Can be kept on the table next to the game board. -They stack even with the lids on. -They're low-profile with a wide base so they're unlikely to tip over. -They're free.
Sometimes there's leftover gravy on them in hard-to-get areas.
Can confirm. I was able to negotiate my way into getting seven of them after only ordering a small bag of potato wedges, and I'm quite pleased. Perfect size and durability, the only thing is that opening and closing the containers is loud and slightly cumbersome.
