I've been searching for a low cost, no craftsmanship necessary, solution for holding my ever-growing stack of adventure cards. I came across these acrylic boxes (originally designed to hold sweetener packets).
These are made by USAcrylic, but I actually found and bought them from Amazon for next to nothing. Let me know what you think. Any better solutions out there? I've seen QRal's work, and those are certainly very sharp looking, but not as easy to get your hands on.
