Binders are a great way to keep paperwork organized for safekeeping. Standard 3-ring binders are the most popular type of binder used in offices, schools and homes because they’re relatively inexpensive and come in different sizes and colors. Some binder covers have clear plastic inserts to allow for customization. Binder dividers keep like items together, and binder pockets allow you to insert and store items within the binder.
