Fibrous casings are clear, unprinted non-edible with a string tied at one end. Fibrous casings allow moisture, air, and smoke to penetrate the casing, making it perfect for any type of bologna, cooked sausage, as well as dry (Genoa salami) or semi-dry sausage (summer sausage) and other cured sausages. Soak casings in warm water for 30 minutes prior to stuffing. | LEM Clear Unprinted Fibrous Casings 10 Pack | Size 2-1/2" x 20"
