As a teacher I needed a binder to keep the work for the semester organized. This can do the trick nicely I actually have two binders a 3 inch master binder and this smaller one that I carry back and forth to class. However when it is full it can hold a lot of pages and get quite heavy. I use sheet protectors and the cover of the binder is big enough that the sheet protectors are fully protected.
I am using this binder to keep our trip logs in. I like to take notes when we travel and then type them up in a day-by-day format and place them in a binder. This binder comes in many different colors and I can also use different stationery for each trip. It makes it so easy for me to sit and read about places we have been while reliving so many special memories.
