Natural hog hank casings - 32/34 mm stuffing size. Preflushed and will stuff approximately 115# of meat. These are the casings I used in my meat buisnesses. They have a consistent size with no whiskers. They cost more than the home pack natural casings because of the better quality. Believe me they are worth the few extra dollars. They are preflushed, soak in warm water for 15 minutes and stuff away. Keep refrigerated until ready for use. Any left over casings put in plastic bag, add some salt and keep refrigerated for later use.
