Sold in packages starting at 5 meters (almost 5.5 yards).We stock both US made and European made bone casing tapes. The US made is very light weight and the European made is incredibly durable. Want double bone casings? Sew carefully down the middle of these bone casing tapes and use two smaller bones! Two 4mm spirals fit the 1/2" bone casings and two 6mm/1/4" bones will fit the 3/4" casings.
