If you're interested in the different variety of match designs, you need a way to store your books open. Lots of designs differ only in the printing inside the cover. For feature matches, of course, you want to see the match-printing as well.

I've found nothing better than thick ring binders containing plastic pages of open matchbooks. I'm looking into getting some snap-lock plastic cases made to hold an open full-book but haven't had time to complete the project. These would be nice for traders or selling at shows and flea-markets.
