25 JC Products Stainless Steel & Mylar Reeds. These are loud voice double reeds - One reed is stainless & one is mylar sandwiched on top of each other. The double reed can be "bladed" (slightly bending the reed up with a razor blade to achieve that sweet sound you are looking for / change the pitch and tone of the call)- Some call makers use this reed (after bladeing) as high pitched raspy cottontail or jack rabbit voice. JC Products reeds are the industry standard and used by almost every manufacturer of game calls (Circe, Primos, Sceery, Modern Call Products, Dan Thompson, Johnny Stewart, etc) . Voice bodies have a true diameter of .200" with a .010" taper for a snug fit. Great deal for the hobbyist call maker.
