There is much to love about Jiffy mailers, especially the ones on this page. They are part of the company's Rigi line, named for their rigid material. They are made of stiff fiberboard and feature a sturdy kraft construction. As a result, the sleeves provide excellent protection for items like photos, floppy disks, cassettes, and more. The biggest ones can even hold calendars. You can count on the contents to be safe because the Jiffy mailers will not bend, crease or fold.On top of that, their design is convenient for shipping workers thanks to the self-sealing flap. Once you insert the contents, all you need to do is fold said flap and the sleeve will be tightly closed. You do not need to expend any of your supplies of tape, staples, adhesive or stiffeners. Using these Jiffy mailers can save you time and money.When you want sturdy and self-sealing Jiffy mailers for your shipping needs, Tigerpak can provide.
