The Match Book Saver is here to help keep your match booklets from disentigrating during those matches where it is less than just sunshine. These are sized to hold 8.5"x11" sheets folded in half and will fit about any thickness of match booklet. 
Vinyl on both sides to view two pages at once.
Water resistant zipper.  
Opposite the zipper is a Hook strip for attaching to any Loop panel on a pack. The Hook strip will act as a PALS compatible webbing attachment or allow you to add your own clip to hang it from things.
