Quality, but missing something...

I was impressed by the quality of the mailer and the quality of the print on it. Especially since it has a high sheen, I was expecting the ink to wipe off easily, or even scrape off, but it stays on. The *only* thing I would like to see is some sort of padding. Since I'm sending books, I don't know how reliable the mailers are going to be with getting my books to customers without any damage.
