What's your favorite binder for 2x2s?
We all have our slabs, mint set boxes, and nice Albums (e.g. Danscos and the like) but we all end up with a ton of 2x2 flips. I could store them in boxes but then it isn't easy to look through. I finally decided to upgrade from the cheap binders I've been using and am curious to hear people's opinions on which binders they like best for coin storage of 2x2 flips. What's your favorite binder for 2x2s?
