The Naked Binder writes about its products here:
Made from100% recycled board, 97% of which is post-consumer waste with no decorations, plastics, toxins or vinyl. The board is acid free, so it won't harm your contents - whether you are preparing for tax season, working on your novel or storing your child's artworks.I just ordered a couple to try them out. They look perfect. I hate all the old vinyl ones I have on my (lowest) shelves! Since I will be starting my new teaching career, I'll be needing more binders, so this is my start.
