This quality product is made from natural dehydrated skin, not a synthetic material. To rehydrate them we recommend a quick dip in wine to wet both the inner and outer skin and fill. As with any dehydrated product the more the skin is in contact with liquid the softer they will become and will be more susceptible to breakage. Ø50mm/45cm - 50 pack approx. 750g meat- each skin approx. 750g meat. Suitable for size #10 netting.
