We are in practice for last 40-years. We have selected and no-selected sheep/goat casing those are cleaned intestines of sheep and goat. We have all calibers and qualities in separate dia-meter as 16.18, 18.20, 20.22, 22.24 and 24.26mm with 'A', 'B' and 'BC' qualities. Our material of intestines are brought from different borders areas of Pakistan whose texture is most strong and color is much lighter than other countries material. We make 91-meters hank as salted and its slippery doesn't go away due to salt. Please try and let's know what you found from us. Thanking you in anticipation. Yours truly, Muhammad Sikandar Bhutta.
