I can't gush enough about these binders.
Let's say they are being used by students. At then end of the school year, simply unscrew the tattered cover, place in your recycling bin, and attach a new clean replacement cover. Zero landfill. Zero plastic.
Before I found these, I searched the shelves of the usual office supply stores for plastic/vinyl free binders - I found exactly none. Another thing I did not find, plastic free binder dividers. But Guided Products has them in sets of 5 or 8 - I'm as thrilled as is possible to be about dividers - super thrilled.
