Sturdy binder. I use these for every project we build for a maintenance manual for the home owner. I also only buy this style for a start to finish paper work for each project for later referance. Yes i also have it on computer but I old school and like hard copies.
This binder is so flexible but at the same time resists the weight the daily use and the rings don't break easily. This binder survives the semester of everyday use. It is worth the price.
