Unfortunately these were just a tiny tiny bit too short (width wise). Papers DID NOT slide in smoothly as with other brands. It took much more effort to insert the papers. Once inserted the protector was a bit bowed and did not lay flat. I am not happy with these at all.
Heavy duty not flimsy work well and last. have used them in the past and they don't yellow or get brittle. They will probably still be around long after I am dead.
I love this product because it protects my documents for years. I am a family genealogist writer and musician. I use this product to protect the integrity of my sheet music my writings and my archival family historical documents.
