C&F Design® Saltwater Permit Fly Case is an emerald-colored fly case with two Permit System foams suitable for crab flies and big crazy Charlie. It was designed in the image of the beautiful emerald sea water. The 8mm thick micro-slit foam can be expected to prevent deformation of the weed guard by slightly lifting the eye side and holding the fly. Crab flies with volume on the head can also be beautifully customized and arranged at regular intervals by skipping slits.
