Quick note in relation to my Poly vs. Kraft Bubble Mailers post:  One clever way to get two or more sizes from just one size of poly mailers is to fold down the top excess of the mailer and use the glue strip to seal where appropriate, creating a snug fit around around your item. This is easily done with a flat poly mailer (Polyjacket) or poly bubble mailer (Airjacket), but is nearly impossible with the Kraft bubble mailers (Kraft Airjackets). Not a huge point, but one I thought worth mentioning. Thanks for reading and Happy Friday!
