Well I don't have any for sale, but I can try answer your question. They're a metal tube that is capped on one end. The coon has to stick his arm down in and either push or pull the trigger at the bottom. The original coon cuffs name brand I believe is a push down trigger. My buddy has a knock-off version where they have to pull up on the trigger. Theres a spring loaded metal loop type hook thingy at the open end of the pipe that grabs they're arm and holds it inside the tube. There is almost zero chewing because the caught part is encased in the tube. All the traditional baits work, jack mackerel, marshmallows etc. Some people set them up like dirt holes, but the hole is the trap buried in the bank. My buddy just baits and stakes his and drops them on the ground and leaves them lay. He's had pretty good success this way and it's faster than digging a hole.
