My daughter used this binder for her entire fourth grade year. Oh boy she really had it packed even carried her Chromebook inside. It was heavy. I can’t believe this thing lasted all year. It definitely shows somewhere in tear, but it really held up definitely worth the price and my daughter really loved the design. The zipper held up just fine as well as the binder clips. I would definitely buy this again. Keep in mind all of the pictures uploaded are after a year of wear and tear. ... show more

This is great for holding lots of papers, files, and writing implements. Works well with the carrying straps and the price can't be beat.

    • The Binder That Could Survive the Apocalypse
Color: E Daisy Light Blue Size: 1 Pack
Let me just say it... this binder is a beast. The Case-it Mighty Zip Tab isn’t just a binder. It’s a mobile command center. A three-ring fortress. A zippered vault for all your academic hopes, dreams, and overdue homework assignments. This thing holds everything. Papers? Obviously. Notebooks? Yup. Pens, highlighters, snacks you’re not supposed to bring to class? Oh yes. I swear it has more storage than my first apartment. The zipper glides smoother than a teacher on summer break, and the handle makes it feel like you’re carrying a briefcase full of secrets... or algebra. The inside pockets are like a secret lair for all your chaotic school supplies. The Velcro flap is oddly satisfying. You’ll find yourself opening and closing it just for fun, like a fidget toy for organized people. And the durability? It could survive being dropped, stepped on, maybe even flung across the room during finals week. Still zips. Still mighty. Still standing. Colors are bold, the material is tough, and you’ll instantly become the most prepared person in any classroom. Or at least, you’ll look like you are. Fake it till you make it, right? Five stars for the Mighty Zip Tab. Because when life tries to throw you loose papers and math tests, you throw this binder right back at it... fully zipped and fabulous. ... show more

I wanted a sturdy binder to keep my son’s medical paperwork in during cancer treatment. This one is perfect! It fully zips closed, so nothing falls out, and it has a shoulder strap, so it frees up my hands when toting around hospital bags and such. I love the fun monster design and was impressed with the expanding file folder section with its own zipper for quickly accessing/putting away paperwork. So far, the zippers and rings inside have held up nicely, but the little pink fabric zipper pull on the small outer pocket has begun to fray since I took the pictures shown here. It’s not the worst that could happen, but it’s still annoying nonetheless, considering that I’ve had it for barely three months and the fraying started after only a month or two. Aside from that point regarding durability, I’m very happy with my purchase. ... show more

My daughter loves this. She is all set for school she doesn’t even need a backpack. She loves the design and there is a lot of room to put a lot of stuff in it. It fit all my daughter’s school supplies in it. It is durable and the quality is awesome. It comes with a strap so she can carry it with ease, and it doesn’t hurt her back. She loves the black hello kitty design. ... show more

This is the most amazing binder/folder trapper keeper ever. We bought it in July 2019 and my kid has used it for all things school. It is like an extra appendage that gets carried around all day long, used and abused. It is stuffed full of papers, pencils, scissors, rulers, calculator. You get the idea. the netting inside ripped but he didn't care and just duct taped it. It even had extra use through Covid because the kids couldn't use their lockers. It just now finally had it's last hurrah in March 2023. The smaller zipper broke and it's time to finally get a new one. we will definitely be getting another one of these. you cannot go wrong with this purchase. it is amazing and well worth the money. ... show more
