I actually purchased what is sort of the equivalent of a photo album for pins back in maybe 2001 or so, at World of Disney in Anaheim. I like this better for display purposes, not necessarily for traveling or for hardcore sellers. It does not zip up or anything. It is just an album with a three ring binder and felt pages. Each page has little squares sectioned off and you stick all your pins in the squares. There are plastic sheets protecting each page as well. I only bought one album at the time to see how I would like it and WOD stopped selling them shortly thereafter, and so did
Disneyland. WDW said they still had some in stock a few years ago, but mainly, the things that are always available for pin protecting and keeping are those little cases that zip up. I used to be a fervent watch collecter and those were tricky to display - you couldn't exactly sick them in an album unless you took them out of their cases - or carry around for selling. Plus, they got to be too costly to collect. But pins are everywhere and easier to display, tote and collect!
