I can't say enough good things about these mailers. Especially the PRICE. I am a composer. My music books are spiral-bound, regular size (8.5" x 11" basically). I can fit a thick book in these, or a few smaller books. I also always add cardboard so they can't be folded by the postal service. Although my books always go into clear plastic bags first, I am glad that these are more moisture resistant on the outside. I have used the orange paper bubble mailers for YEARS. They do get pricey. When I wanted just 25 of them recently, I found these and bought them because of the price. Now that I have them, I know what a great decision that was.
