I received my package very quickly. The peepers were the nylon pin type. They were very easy to "install". They seem to be effective so far. My male turkeys were fighting and I purchased these after they suddenly killed one tom. I have had no fighting or injuries since I put the peepers on. I have naragansetts and I was worried the peepers would be too small but they fit even the large toms very well. Overall a very effective product.
