## Questions & Answers

**Q: is the fabric on this binder water resistant?**
A: We ordered them for our fleet trucks. They are really durable and the manager is really impressed and happy with them. I think they are water resistant because we keep all the important paperwork in them. But I am not positive.

**Q: Does this fit in a backpack?**
A: Yes. In a large backpack. My daughter is 6th grade. Her middle school requires all students to carry a 3" 3 ring binder to each class period. All the students carry these around using the shoulder strap. She carrys this with 7 spiral notebooks, 7 folders, 2 marble composition notebooks inside, zipped up and it fits in the large Jansport backpack to and from school.

**Q: Does it have a shoulder strap?**
A: The chart shows it comes with a strap

**Q: who makes it?**
A: The brand is "Case-It."  I've never heard of it before, but 3 weeks into the school year it's still looking new.

*by D***. on 3 September 2024*

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.
