I use binders for all kinds of organization in my classroom and these are quite colorful and also pretty durable. I do have to say though that the inside "folder pockets" are pretty flimsy and tear easily.
My daughter switched to these binders and now we only buy Staples Better binders. They take the all the abuse kids dish out. Worth the extra expense. they last all year sometimes two or more.
I really like this product. I love its rubbery seams. My kids can't destroy this binder! The only negative is the clear cover on the front can rip off easily.
My son has used these notebooks for 7th & 8th grades and they lasted the whole year. Now we are trying the larger size for high school and see how they stand up.
This is the best binder I have found. The d-rings keep my pages flat and they stay closed when I turn pages. You can place tiles on the end and front page.
