These strips have black dyed bars across them. This new pattern has been variously called Black Barred, Grizzly Barred or Tiger Barred. They mimic the barring found in nature on such fish prey items as, sculpins, crayfish, squid, shrimp and lots more. They are used to tie Brian Silvey's deadly new Tube Snake patterns, such as the ones shown below. The standard strips are 1/8" wide and include 4 strips per package, approximately four feet total.
