Pro Gammarus Shell Back is made of durable vinyl. The Gammarus is a bug small in size but big in importance and found in both fresh and saltwater. This fact makes Gammarus flies a permanent part of any serious fly box and the Pro Gammarus shell assists in making lifelike imitations with ease.

Pro Gammarus Shell Back features:

• Shell back material for tying gammarus imitations
• Can be used for both saltwater (seatrout) and freshwater flies
• Attach with ribbing
• Can be coated with UV glue for more three dimensional appearance
