Also it will not have the taste of casing. Some buyers mentioned it's easy to break when they fill the sausage. And they may not pay attention to the filling method or using the tube to fill the meat too fast. When stuff the meat manually, you can do it by separating some small parts. Then you use toothpicks to make the small air bubble after finish filling.
