Nice product, but missing important part.

This binder just arrived today. Got it all set up for my son and went to zip the main body part and the zipper pull is missing. If he didn’t need this desperately, we would send it back, but I’ll just use a key ring in the pull to make it work.


It was the perfect size for all of my notary supplies. Fits perfectly in my bag as well.

Great BINDER/School Bag!!

I love love love this bag! My son who's 13 years old doesn't even need a backpack because he can keep all of his items in this bag and carry it around with the strap! Very sturdy everything *so far, had it for about 3 weeks now* also, it has a very long adjustable strap with a shoulder pad thing. Now, because of all the notebooks and folders that go in here, you can probably get away with having a couple thinner books like 2 inches each and the zipper close perfectly fine. Why I gave it a 4 star is I wish the zippered storage area had more slack to it.. its a little on the tighter side where you gotta flatten your hand to get things out... but you can always keep a pencil bag in this bag too though!

Perfect size

I love how big this binder is. I needed it for a large amount of paperwork (500+ pages) and there is more than enough space to keep things organized. I love the shoulder strap as well, it makes it so convenient to carry plus it’s really sturdy. Couldn’t ask for a better binder.
