Ring binder

A ring binder is like a special book that helps you keep your papers organized. The book has a spine, or a back cover, and a front cover. Inside are round rings that can be opened and closed like a door. You can put your papers inside the rings by putting holes in them with a hole punch. The rings hold the papers in place so they don't fly away. You can also add dividers to help you separate different types of papers. It's like having a special secret book just for your important papers!
