Does anybody know of a toploader and sleeve that exists that would be an ideal size for individual Wacky postcards? The toploaders that are a bit bigger than 5 x 7 on the outside leave too much extra room for my taste. The next standard size down seems to be a bit over 4 x 6 on the outside. These are just a hair too narrow for the Wacky postcards. I have a beat up old toploader that measures a bit over 5 x 6 on the outside, but I have no idea where it came from. While it's not perfect, this is the best size I've seen yet for these postcards. Does anybody know where to get toploaders and sleeves around this size?
