A very unique casing because it is made using plant products only. You may use on any sausage be it vegetarian, poultry, beef, sheep or pork. The casing are best for fresh sausages. You can cook or smoke if you lay on racks as I sometimes have a problem with them dropping in the smokehouse if the humidity is high.  You will receive 50 full strands ..   We always save you money as a direct importer.YOU HAVE BEEN ASKING FOR DIFFERENT SIZES,  WE NOW HAVE  23mm, 26mm (HOT DOG SIZE) AND 32mm.
