The Three-Ring Binder  A three-ring binder is a great way to organize small electronic components and a thin one will fit nicely in most bags. All you really need beyond that are sports card sleeves, as those provide a good amount of room for things like flash drives and cards, membership cards you don&#x27;t want to keep in your wallet, sticky notes, and many other small things you don&#x27;t want rolling around just anywhere in your bag.
