Are case it binders good or bad?

They're good. Case It Binders have handles and a shoulder strap so it's easy to carry it with you anywhere. They come with built-in tab file folders, pencil cases, and other useful areas to store and organize your items. They have "hold-down pages" which allow you to secure each side individually. Most importantly, the zipper keeps everything inside.

Some Case It styles - the Dual-100 and Dual-500 - have two sets of rings which let you hold twice as much as a standard ring binder.
