This set is made up of one sandwich bag and 2 snack bags.
The fabric is Laurel Birch Dancing Horses 100% cotton , and the lining is food safe ripstop nylon. The sandwich bag is made the exact same way, just large enough to accomodate almost any size bread.
The snackbag is about 4 1/2"x6" (12x15cm), and has a zipper closure. The sandwich bag is 7" square (18cm) and also closes with a zipper.The lining can be wiped out with a damp cloth, or you can machine wash the bag when needed.
