WOT I4-Pack Telescoping 3 Ring Binder 1 Inch, Expandable Flexible Binder - Patented Design for Easy Portability, Holds 225 Sheets, 4 Bright Colors, Perfect for School, Office&Home Organization

These are actually really cool. I ordered them for my softball team to keep their notes in. They are durable and slim. They are easy to use to take notes in. Definitely worth the money

Great binders. Worked great to make my elderly relatives a large print address book. I love the D rings, they hold a lot of pages. They're very sturdy but lightweight. Even my tiny but spry 92 yr old Mom likes them and hasn't destroyed one yet!

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.

Very high quality, very well engineering, very strong , practical and well designed.

these were really too wide for my purpose; way too wide. But they have really great colors. I was going to use them with filler paper that I purchased in almost the exact same colors to help me organize my thoughts, segregating the different contents.Realizing I wanted a different size, I returned. If I had been using them for, say vehicle transport to school, I probably would've kept them.

Quality product. Very convenient.

Works as intended, with reming unwanted space compared to traditional binders. Durability is great for heavy use and the color being neutral allows these to be used for any type of job. binders open easily and expand as you need them to. Highly recommend.

I like that the cover folds back easier to write very clever.
