Case it Mighty Zip Tab Zipper Binder — 3" O-Rings, 600-Sheet Capacity, Midnight Blue with 5-Tab Expanding File

The Case-it Mighty Zip Tab School Zipper Binder is a durable, all-in-one organizer that stores up to 600 sheets and includes a built-in 5-tab expanding file for color-coded subject sorting.

Students who move between classes, extracurriculars, and study sessions need a binder that keeps papers, pens, and small essentials together and protected. This zippered binder combines a large 3" O-ring capacity with a sewn-in 5-pocket expanding file, multiple zippered compartments, and comfortable carrying options — all in ripstop fabric built to resist everyday school wear. It’s designed to make switching classes faster and homework more manageable without letting loose papers scatter in backpacks.

How does the expanding file simplify class organization?

The integrated 5-tab expanding file allows students to separate subjects by color and access important handouts quickly without unzipping the whole binder. Each pocket is wide enough for standard worksheets and smaller folded items, so you can keep tests, homework, and permission slips in order.

• Five labeled pockets for subject separation
• Quick access to papers without unzipping entire binder
• Holds full-size sheets and folded handouts securely

Will this binder hold everything a busy student needs?

Yes — the 3" O-rings accommodate up to 600 sheets, while interior and exterior zippered pockets keep pens, calculators, and personal items organized. The layout prevents loose supplies from falling out and creates a compact, grab-and-go system for packed school days.

• 3" steel O-rings for up to 600 sheets
• Interior zip pockets for pens and small supplies
• Exterior zip pocket for quick-access items

How easy is it to carry between classes and activities?

The binder offers a built-in handle plus an adjustable shoulder strap so students can carry it by hand or sling it over a shoulder for comfort. The balanced design and durable hardware help distribute weight so it remains comfortable during longer walks across campus or between practice and class.

• Sturdy top handle for quick pickup
• Adjustable shoulder strap for hands-free transport
• Reinforced stitching at stress points for durability

How durable is the material for daily school use?

Constructed from ripstop fabric, this Case-it binder resists tears and fraying typical of heavy use. The zippered closure protects contents from spills and dust, and the reinforced ring mechanism keeps pages aligned even when filled to capacity.

• Ripstop fabric resists rips and abrasion
• Zippered closure protects papers from spills and loss
• Durable ring assembly holds sheets securely

Who is this for? The Case-it Mighty Zip Tab School Zipper Binder is ideal for middle school, high school, and college students who juggle multiple classes or activities and want an organized, portable solution. It also suits tutors, home-schooling parents, and anyone who needs a rugged, all-in-one folder-and-binder system to keep paperwork, pens, and small essentials sorted and ready.
