My husband was in need for 3 inch binders so I got him three different colors so he can figure out which is which. He is very active and the 1 inch binders are bulging at the seams so the 3 inch ones should last a while.
The Staples Heavy-Duty Binder is an excellent choice. However it loses a star because it doesn't have a plastic cover to slide a sheet to decorate or label it.
I work for a small medical practice and have purchased about five or six of these binders in various sizes. They're extremely sturdy spacious convenient and are extremely durable. I've never had to replace any of our binders--just expand on the number of binders we need for our practice. I love the vinyl slots on the cover as all our binders can easily be titled. The ring mechanisms are very smooth and operate with very little effort and always stay in alignment. These are definitely worth more than any brand name binders I've ever purchased. I would easily recommend these binders to anyone looking for a fine quality in binders.
I always buy staples binders and office supplies. A local store opened up in Menifee a few years ago and it is much closer for me than the store in Lake Elsinore which was the closest until Menifee opened. I also do a great deal of genealogy work in which I store many related items in Staples plastic sleeves.
