My daughters use these binders for school. At the end of the school year the binders are still in great shape. They last for many years unlike department store binders that fall apart half way through the school year.
My son has demolished 3 binders this school year alone each one labeled heavy duty and costing me a heavy duty penny to go with the title. This binder has finally beaten him. There is no sign of wear after 2 weeks- a significant feat in the hands of my little abuser. Also the rings still meet to keep all the papers in since he cannot manage to use the releases the proper way and just pulls in the middle. I have great faith that this is my new product of choice for many school years to come..now I just have to make him understand he doesn't need one in every color!
Single use Trigger Finger Binder Ring opener. I've had this for over 6 years. Due to the fact that it has rubber hinges and edges it resists falling apart and splitting. Awesome!
