    • Love it!
Color: Light Pink Size: 1 Pack
This is the perfect binder for school. It can hold a lot of things, I also love the color. The only problem I had with this product is that the mesh pencil case on the inside ripped quickly. Other than that, the binder is very durable.

    • This is a very big binder
Color: S Z-purple Size: 1 Pack
Before you buy this, make sure to read the specs because it is very big. It is exactly what I needed to contain things for my business, there are lots of nice little storage options and a ton of 3 ring binder space. I'm keeping various things in the inside storage areas, business cards in the outside storage, lots of papers in the according area and can carry it by itself or in one of my bigger travel bags. I like the design and color, its very me, and everything works and closes correctly. It is sturdy and I expect will last me a long time. ... show more

    • Great Binder that Every Kid Should Own
Color: E Fire Engine Red Size: 1 Pack
The headline says it all. It's a great binder, and every kid should own one. This binder has helped my two middle school boys tremendously. It taught them to be organized (and one kid was extremely disorganized). They can keep subjects separate. The binder holds multiple notebooks, folders, dividers, supplies, even some textbooks (the thinner ones, not the huge textbooks we lugged around as kids). My kids literally carry all subjects in this one binder. They no longer have to stop at their lockers in between classes and rush to class. Yes, it does get heavy if you're loading all subjects into this binder, but it is worth it and my kids have never complained. They absolutely love it, and other friends have asked where we get this so they can also get for their kids! It's really great, because it zips shut so nothing falls out, even if you store pencils or markers in it. The binding is very sturdy, and has lasted all year. I do switch it out at the beginning of the new school year and buy a new one. Not because the old one broke, but just because some edges can get frayed, and my kids enjoy starting each year with a fresh clean binder. Please buy this for your kids if they're in middle school. It is a life saver. ... show more

    • Has held up to intense daily use, but won’t last forever
Color: E Fire Engine Red Size: 1 Pack
Review Image by Beevan Beevan
This product has worked well for the kids at school. The amount of paper and notebooks that it is possible to fit inside is impressive. My son uses the shoulder strap to wear this in addition to his backpack although it would fit comfortably into most standard backpack sizes. The fabric on this is rough and tough and has taken a lot of use, but it is definitely showing the wear. The handle is starting to fray and I suspect the strap will not last for very long. That said, I would purchase this again as I didn’t expect it to last beyond a single school year before needing to be replaced. All things considered, it has held up well. My son overloads it to be sure and under these conditions, it has surpassed my expectations. The red color is vibrant and easy to spot, which may help one to not leave it behind accidentally. ... show more

    • Great School Binder!
Color: R Z-black Size: 1 Pack
August 2013: I normally wouldn't write a review for a binder that has ~134 reviews, but this has gotten some negative reviews and I feel this is a good binder. I have 2 kids going into 7th and 9th grade and they need "giant" binders because every teacher wants them to have a tabbed section for their class. So, I have had experience looking for binders that are 3.5" wide at the spine, or larger, for 3 years. This is my 4th year. These types/styles binders are not always the most durable. Twice, I've had to purchase a new binder 1/2 way through the school year or sooner. My kids haven't used these yet, but just looking at this binder, it seems more durable than many I've seen and/or purchased. The 3 rings, and the "tabs" on the top and bottom for opening the rings, are metal. Last year, my sons' binders had metal rings but the tabs were plastic, so, of course, they broke. This shouldn't be a problem with the metal "tabs." The hard cardboard or plastic (I don't know what it is) that makes the front and back covers stiff, and is covered with the "fabric" is quite stiff. I'd say stiffer than some past notebooks my son's have used. So I expect it to hold up better than some past binders. This notebook also has a nice handle along the spine, as well as a long, adjustable strap, for carrying the binder, if you don't want to put it in your backpack. As far as this binder not fitting into a backpack when several large textbooks are present (as another reviewer stated), the solution is to purchase a large backpack with a large base/bottom. For example, this binder fits just fine, with room for at least 3 text books in the Dakine 33-Litre Campus Pack Dakine 33-Litre Campus Pack and Dakine Campus Laptop Backpack whose base/bottom measures 9.5"X8" and widens to 13" in the middle. A school backpack's base size is important, not so much the volume. I know this because I've tried other packs that had the same, or larger, volume. But they didn't work as well for school packs because its the base/bottom size that is more important for carrying books (as opposed to camping, hiking, etc.) So get the right pack. i do agree with a previous reviewer, that the accordion file section is a waste of space. But, it doesn't take up that much room and can easily be cut out with scissors. UPDATE (October): 1 quarter down (and 3 to go) and these binders are still looking good and functioning as they are supposed to. No problems with the rings. No fraying or missing edging. No rips/tears/etc. UPDATE (December): Well, the semester is almost over (1 week to go) and this binder has held up like a trooper. And boy do I mean that. My high school freshman has his jam packed. And, when I say "jam packed," I mean it is full to it's limits! Over Winter Break we will go through it and file away things he doesn't think he needs anymore in his desk, so he has room to "jam pack" it during the second semester. All bindings and everything are still intact. The 3 metal rings are still working. UPDATE: May, 2014: School will be out in 3 weeks and this binder is still going strong! My kids might even be able to use it next school year. Great purchase and value! UPDATE: January 2015: My younger son is using his same binder from last year and we are through the 1st semester and it's still going strong! My older son wanted a new binder (Actually 2 smaller ones because he has "A" and "B" days in high school and that way he only needs to carry 1 smaller binder, for 3-4 classes each day, rather than one large binder for 6 classes. I bought him 2 of the same brand, just smaller/thinner.) But "oooh" and "ahhh" to THIS binder. 1.5 years and still going strong! Final update: March 2016: I only buy this brand for my boys now. They are truly amazing. My younger son used his 1st one for 1.5 school years and then something happened to the rings (which might have been his fault - I'm still skeptical), so I bought him a new one. If I was in a financial "pinch" he would have kept using it, as it was more annoying that unusable. Since this initial purchase, I have bought this brand from Amazon in various sizes, depending on my kids' needs, and they are all equally durable. Thank you Case It for finally making a durable binder in a variety of colors and sizes! ... show more

    • Pink case it zipper binder
Color: Light Pink Size: 1 Pack
The zipper binder has lots of room for storing loose papers and organizing them in tabbed dividers. Also 3 ring binder holds lots of loose leaf paper and flyers. Mesh pouch holds pens and accessories. It is sturdy and well made. The price was nice for the features. It is also great that it has a long carrying strap. The pink color is pretty and reminds me of Barbie. ... show more

    • Good binder, Weak zipper
Color: E Fire Engine Red Size: 1 Pack
Binder is very sturdy. Suits the needs of my 5th grader well. Unfortunately, the side zipper will not stay closed. His things have fallen out multiple times while trying to walk through the halls. Would not buy this design in the future.
