1 Inch Telescoping 3 Ring Binder 12 Pack, Expandable Flexible Binder with Customizable Front Cover & Clear Catalog Pocket, Holds 225 Sheets, Assorted Colors, School Office Supplies

These 3-ring binders are awesome! I love that they have an inside front pocket with a tab at the top that keeps the papers in place. I also really like that they are expandable. The front cover has a sheet sleeve. Oh, I love the thumb cut-out on the back cover, which helps in opening the folder. They are made very well and are holding better than any other folders I have ever used in my life. I also need to color things, so the four different colors are great too!

Love this binders, well made, good quality, beautiful colors, and had them for a couple moths and still holding great. The price was good and I recommend them!!

The binders are great. I use them in a retail environment and find them to be extremely durable. They also save a lot of space.

Works as advertised. I wish it had a tab to open the rings. Pulling them open is a bit difficult.

As a high school engineering teacher, these binders are great for the classroom. They are durable, easy to open, and best of all does not take up a lot of space in book bags! The organization makes the binder easy for all types of students and learning styles! I even bought them for my own children to use!

I love these. Super practical. The only thing to consider would be to make the rings larger so I can actually flip more than 50 sheets in it. It doesn't fit 150 sheets. At best it us more like a 70sheet binder but the rings are not very large so it won't let you move around the paper easily at the full capacity. If you put two pads of 100 sheets, they will fit, but you won't move them at all. That is the height of the rings, very small. I have rather thin sheets in pads for engineering so they are compact. I may take pics at some point. For now, I use these binders for materials for my classes and it starts getting crowded at around 20-30sheets. But, super practical to use, though. I will just be removing each exam section to a larger binder i suppose. No way you can fit there all stuff for science classes from 1 semester, but you can transfer them after each exam to another, larger, binder. Wish they had larger rings as well to kind of use them both, because the design of these is great! You will really enjoy this binder. Super nice quality and it probably will last for very long time. I got the ones with a pocket in front at 12 binders in a set. Will probably use these also for training purpose and give these away to students with experiment setups. A note to the company: consider larger rings that actually can fit those 150-200 sheets, not pages and use a binder with that amount in them. Lol. Try it and tell me it works. It is a nice binder, but it needs that one more option for those that plan to use it more actively and keep adding more notes or print-outs in it.

I bought these for my son who just started college this fall. We didn't want to weigh him down with those huge, bulky 2-3 inch binders plus books, supplies, and his laptop. These came in clutch! They're pretty much flat like folders, but expand up to an inch as you fill them up. He's already at midterms for this semester, uses them twice a week, and has barely even filled them halfway. They're deceptive in how much room they actually have to fit what you need to carry. The material and rings are very durable. The colors are vibrant, too. These were a bit pricier than buying the typical 1-in binders, but I was willing to pay more to keep him from having to lug those around. Highly recommended!!

Durable and compact. Exactly what we needed for a busy trade show.
