I have used these for over 6 years and you can't find any better. They are durable and last for a long time. I have some that have been in use for 6 plus years being used everyday and they are still being used today.
Having moved into a new residence 3 years ago never quite set up a filing system for important papers due to becoming a caregiver to a terminally ill spouse. Since that has passed I am now determined to eliminate/dispose of unncessary paper & use these file folders which will be kept in Staples bankers boxes.
