I bought a handful of casino chips on eBay and 3 chipcos were included. Honestly, I kind of assumed I'd toss them. But I cleaned them with the other chips, and as they were drying, i started playing with them, and all of a sudden I found myself thinking, "well I definitely need more of these." And then I managed to convince myself to stop being crazy. But this morning, I found myself searching for chipcos on eBay.
