Natural casing  
Human being has always paid attention to natural casing and has always been able to appreciate and make a good use of them, not only for sausages. Evidence prove it:
  • As a container. Casings have been used to carry water.
  • As decoration. Casings have been used for lamps, drums, and other traditional musical instruments.
  • As a tool. Famous Argentinean "boleadoras" are made of dried natural casing.
  • For leisure and sport. Guitar strings and tennis racquets cords have been made with natural casing.
  • As surgical material. Natural casings are processed and used for stitching such as it happens with "catgut".
  • Prophylactics
 
However, with no doubt the main use of natural casing is natural or cured sausages.  

Spain, as a big consumer of sausages produces a wide offer of then in calibre and quality and in fact Spanish sausages are a synonym of good quality.
