Great Binder that Every Kid Should Own
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.

Very sturdy can stand up to a middle school boy!
This binder is sturdy! It has survived two years of middle school, being stuffed to the brim, thrown around and still looks great. It comes with dividers to help organize lose papers as well as a compartment to put extra pencils and supplies. I worried it would be bulky but it is just the right size for all the many classes and holds all the needed supplies easily.

Great customer service
The top zipper broke 2 months into school. UPDATE: I contacted casit customer service and they were very responsive and shipped out a replacement very quickly!

Fine Binder if You Have a Heavy Student Workload
I purchased this binder because I needed something large to handle printouts and notes for several classes at one time. I didn't want a standard 3 ring binder; I wanted something with a strap to make carrying it around easier. I settled on this one because it came in a variety of colors, had the features I was looking for, and fit my price range. The outside of the binder is soft and durable. From what I've experienced thus far, it wipes clean with a damp cloth or handy wipe. The zipper that opens and closes the binder is strong and I've not had any issues with it catching, getting off track, or having trouble closing the binder. The zipper is strong because I have had the binder to capacity and it still closed it and didn't fail. There is a handle on the spine of the binder that is very well made and securely attached to the binder. I love the purple color, which was one of the big selling points for me. There is a zippered pouch on the front of the binder that is only a half pocket. I wish this pocket was full-sized so a piece of 8.5 x 11 paper could fit into without folding it into quarters. Inside the binder the rings are large enough to hold papers for four information-heavy classes. There are five pockets that can hold standard size papers and a zippered pocket that can hold pens, pencils, a calculator or whatever else you need to carry. These pockets are held closed by a velcro strap. I've found that you cannot pack the zippered pocket with too much or it won't close. I generally carry all my notes, highlighters in the zippered pocket, papers and a steno notebook in the five pockets, and a textbook in the binder and it will zip up around all of that. Note: if you pack the binder full, the covers will kind of bend in when the zipper closes but I've not had that zipper fail yet! My biggest complaint with this binder, and the reason I didn't give it five stars is the the carrying strap. There is a small bit of padding on the strap to make it comfortable on the shoulder. This padding moves around on the strap and I don't really find it making throwing the binder over my shoulder any more comfortable. The more that's in the binder, the more uncomfortable it is to carry. I usually use the handle on the spine of the binder over the strap. Overall, I am very pleased with this purchase and, if I end up needing another binder I will be going with another one of these.

This is the binder your middle schooler needs!
This is a must for all middle schoolers. When my son started, we tried the usual 3 ring binder but having to take it out and put it back in his small string backpack got to be too much. This saved us and has been so sturdy! The handle holds all the weight of his papers and items FOR THE WHOLE SCHOOL YEAR! While other brands break, this brand held up for us. It has tons of storage, comes with class separators and is easy to carry between classes. I like knowing they are prepared and he feels seen in whatever color he wants. The colors are true and well made. Can not ask for more!

Got this to be a travel kit for my extra-prized Magic cards. Easily fit about 100 Ultra Pro 9-a-page card sheets, with the majority of the cards double-sleeved. Plenty room left. Has pockets that I use for empty sheets, assorted pamphlets and booklets from Magic fat packs etc. I truly doubt the rings would ever open in transit, but the zippers give me piece of mind. Canvas seems very rugged and the handle is super.

Bought for my child who needs to carry a heavy binder in school. Its handy and looks good. Quality seems ok but material could be thicker. Not sure it will last too long but time will tell. Shoulder strap is not patted at all.
