WOT I Telescoping 3 Ring Binder 1 Inch 4PCS, Flexible Binder with Expandable Spine, Customized Front Cover, Holds 225 Sheets, School Office Home Supplies

I was looking for something that wasn’t bulky to fit in my bag, it’s thin and light but seems durable.

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!!

I love these binders. I have bought about 5 packs of the 4 folders already. I use them to hold sheet music and they can hold a lot. They are sturdy but bendable and they look professional....I got them in the color black. The price is worth it because these really are the best binders. Only complaint I have is that they dont have any bigger to buy.

Great for keeping things in order, opens flat.

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.
