This is a handy little trade binder for keeping a small set of cards handy. It's your typical UltraPro binder, so it's relatively sturdy and holds standard trading cards. These little binders are nice for tossing in a backpack when you don't need your whole collection. I don't typically play at events where sideboards are needed, but I hear they're good for that, too. It's also nice to have a little binder for sticking valuable cards in after opening packs at your local shop, then you can get them home and store them safely wherever you put the ones that are going to put your kids through college someday. (Ha. If only! I'm looking at you, guy who sold The One Ring to Post Malone!)
