Besides the binders that I use, These are a very imnportant part of my chip storage methods.

On the side of each box, I have made labels to identify what's inside, i.e., Nevada Obsoletes, Caifornia/Washington. When stacked up 6 high, it makes finding the right box Extrememly easy. I've seen collectors and dealers use boxes without anything to help them identify whats inside, and waited while they go through box after box trying to find the chips they're looking for.

Maybe it's just my organizational skills from work in action, but for me, labels on the front of the box is essential!
