Hog Casings for sausage making with a filled diameter between 32-35mm, about 1.25-1.35 inches. Sold by the hank, and packed fresh in salt. What is whisker free? Some lower quality casings have these long threads the come off the casing, and lead to an unpleasant texture and appearance in the final sausage. Our casings do not have these threads lining the casings.
