I received a piece of this stuff with my new box call. It makes a wet or damp call work! I dint know exactly how but it sure does. The outside is white and you use that on your box call surface and the center is a reddish color that you can use on your friction striker to make it work in the wet. dint know how it does it but it works well!!! I tried it on my old Graphite Prospector box call and it really does work.
